Gmail not syncing across devices in apple mail app

This is still a huge problem for me as only my phone is syncing properly with gmail. iPad and MacBook do not. All worked perfectly fine until about a month ago . I have tried a bunch of fixes but nothing working .Please let me know what you find out - I would VERY much appreciate it!!

I have 3 gmail accounts. I am signed in on all 3 of them on my iphone 13 pro max, iPad pro and MacBook pro. All devices are up to date. ONE of my 3 gmail accounts has a syncing problem: Details. If I work on my MacBook on that one problematic account, e.g.. if I write an email, save an email in drafts or delete an email, it DOES sync to my iPad and iPhone. the opposite does NOT happen however. e.g. if I work on my iPad and/or iphone, it does NOT sync to my MacBook. So my MacBook "talks" to my other 2 devices but my other 2 devices do not communicate with my MacBook. Apple support spent an hour with me yesterday and couldn't figure it out. Should I be reinstalling that problematic gmail account?? Any other suggestions?

Spent a bunch of time with Apple support and it looks like it’s a gmail problem not Apple Mail. If we try the sync with emails sent to my Apple iCloud email, everything syncs smoothly; emails to gmail address do not sync. Google has changed something and I will have to talk to them unless someone finds solution first. I have deleted all email addresses and reloaded and updated all software without results to fix problem.

1. All I had to do was open up on my iPhone 13 into the settings
2. In the search bar typed in "Accounts"
3. Select Mail -> Accounts option
4. In the Accounts view look towards the end and in the Fetch New Data, changed the setting to PUSH

Solve my problem instantly. Do this across your other apple devices

On my recently updated iPhone (Dec. 2023) iPhone does not show PUSH as an option for any email account except iCloud. All others have Fetch only, and they do not show the range of servers that will be fetched (drafts, sent, inbox etc). I wonder if this has to do with Workspaces. Even on a PC, one is unable to drag content from one Workspace to another, they are isolated islands of content.

depends on where things were broken. for me it was my iphone and 99% of my email management is on my iphone. so everything i deleted on iphone did not get deleted. as a result, Mac and Web were "out of Sync". so once i deleted and reinstalled, i had hundreds of unread emails.

On an ios phone or tablet, under the "Mail/accounts/fetch new data" make sure fetch is set to manual.

It seems IOS updates sometimes reset this to "automatically" which even indicates right there that it will only fetch new data when on WiFi and plugged into power. That's one reason it won't resync with Gmail. When set to manual, when you open the mail app or drag down to refresh the inbox, it's manually syncing and will do it properly.

Hope it helps.

Hi. Im not sure if this already has a solution if it would help anyone. What i did. Open Gmail App > Tap on you profile icon > Manage accounts on this device > tap on the slide button > Done > Sign in > tap on the slide button > Done.

I was finally able to get mine to sync. I went to:

• settings
• mail
• accounts
• click on which mail account you want
• account settings
• advanced
• moved discarded messages into deleted mailbox
• Archive mailbox to the archive

I was able to fix mine after doing all the other standard things, I went again into settings, mail, and selected the gmail account. Deleted it and then added it again (make sure you know your password to account). It now works smooth as silk and the iPad instantly updates the iPhone. I tried this earlier but software was earlier version so maybe had something to do with it not working first time. You may have to do this on all your devices. It was getting to be a real pain… but now back to way Apple products should work… seamlessly. Good luck

worked like magic! I also began by trying to delete the account from the Mac and it didnt work.

after reading what you said about deleting from the iphone, i tried it and it worked! everything syncs.

oh the little joys of life :)

Hi, I was going to try this but when I hit delete, Apple gives the warning “contacts, calendars etc affiliated with this account may be deleted”. Do you know how to see what contacts are affiliated with an account? I don’t want to delete the account to solve the mail issue and wind up causing a whole other issue!

My issue is the iPhone mail app keeps saying I have over 200 unread messages when in fact I have none unread. When I delete the read messages the count doesn’t go down. The gmail app says 93 or whatever which is probably true. I review and clean out the other mail app which is what is saying 200 unread. I’m so frustrated. Hours with Apple support to finally say it’s a google/gmail issue and it’s impossible to get support from them.

im fearful to delete any app. I’m not techie!

was that the issue you were having with syncing? This started about 2 weeks ago.

thank you.
