Outlook ang Google calendar widgets connection drop on Poco 1

[musabetes]

I have Outlook calendar, Outlook email and Google calendar widgets on my homescreen. At least once a week they drop off all connections to servers and became blanco. They also stop responding and it's impossible to open Outlook or Google then. The only way to make widgets work is to reinstall them on the homescreen again. Rebooting the phone also removes them from the screen. This is very frustrating bug as I need to check email and calendar every day. Any suggestions how to fix this, exept factory reboot?
