The last 2 updates to this app have prevented my Gmail accounts from syncing with all my devices. After 24 hours the problem seemed to resolve itself. Then just updated the app again and now once again the email accounts won't sync across my devices. Never had this problem in the the 10 years I have used Gmail. I received a standard response about correcting the sync problems. All those have been performed on all of my devices & nothing works. Last time the problem resolved itself. Waiting.
