Gmail not syncing across devices in apple mail app

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.

i have been dealing with this for a few months and it seems that it is merely a sync issue on the google backend. Essentially, the backwards sync from phone to gmail smtp server broke and needed to be reset.

Alas, the fix is to delete the gmail account from your phone and reinstall it. that should fix the sync. that bad part is that you have go go back through everything you have deleted since the break and re-delete, etc.

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 gave up and started using Spark which syncs across my iPad and iPhone. There is a paid version but the free one does everything I need.

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 am afraid it's going to take deleting your gmail account and re-installing it. I'm afraid to do it alone- I was going to go ask for help at the Genius Bar but my son says he'll walk me through it. wish me luck

i have the same issue that just recently started

Same. I’ve tried everything and it’s incredibly frustrating.

I’m having the same issue, have you found a fix?

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.

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.

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?
