Iphone and Gmail not syncing
I have 2 phones...an Iphone 11 and an Iphone 7plus. I have my gmail on both phones. (not the app, use the mail feature) The issue is the gmail is not syncing correctly on my iPhone 11. I will read an e-mail or move it to a folder on my iPhone 7plus but it will not update on my iphone 11. It still shows an unread message or the e-mail still in my inbox and not a folder on the iphone 11. It does update in my browser and on the iphone 7plus. I did recently just update my iphone 11 today, but I updated my iphone 7plus days ago will no issue.
I've tried restarting the phone, as well as deleting the e-mail account and re-adding it. Nothing helped.
Please help! This is my work phone and the e-mails are all over!
