Up to 2 days ago, (August 22,2019) the email app worked just fine syncing with Gmail, whether on wifi or not. Today, it won't sync Gmail unless I'm on cellular data. My other email accounts sync fine on wifi, just not Gmail. Gmail tells me that there is no connection when, in fact, there is.
Any setting to tell Gmail to be able sync using wifi too? This was never a problem before.
I don't know how to put it in safe mode.
To boot in safe mode:
Thank you for that information. If the e-mail worked correctly in safe mode then it means there is a third-party app causing the symptoms you are experiencing. Have you downloaded any new apps recently?
