Past few months I've been dealing with issues where the app doesn't sync emails and calendar just disappears.. it's been happening more frequently lately (it's happened 3 times the last week). I know it's not a domain issue because I have multiple emails.accounts and it happens for all of them. Resetting the accounts, restarting my phone,clearing the cache, switching between wifi and cell network doesn't work. It just randomly starts working again on its own.

Until recently I've never had any problems with this program. But I now have two major problems. When I open any email, It scrolls to the bottom of the email. driving me crazy. The other is I'm not being notified of my appointments on my phone. All of the notifications are configured properly, and when this happens, I will look at my widget and the calendar is showing as yesterday. This has caused me to miss appointments.

Not sure if anyone else is currently dealing with this, but the app won't upload new emails and keeps prompting me to login to my account. Unfortunately, that hasn't been working, forcing me to uninstall and reinstall the app in order to receive/send any new messages. This started about 4 days ago. I've been using the app for YEARS without issue until now.
