Hello,
I keep receiving this pop-up notification on my iPhone. I have various Gmail accounts, and they are all linked in the Mail app. This means that (i) I do not know which account creates the problem; (ii) I do not know how to fix this. Any feedback on that would be very much appreciated.
Thank you!
iPhone 7, iOS 13
What happens when you click the "Details" on the error popup message (See the Pic below)
Best would be to Delete and Add the email account that is creating the issue.
You may also try changing SSL settings
Settings > Password & Accounts > [Select the Mail account} > [Tape on Account with the email ID} > Advanced > SSL Settings > [Disable]
Click <Account (in Blue)
Click on DONE (in Blue) when exiting in the previous screen
"Cannot verify server identity - The identity of 'calendar.google.com' cannot be verified"
