Hi all,
I have managed to fix this on my computer. Issue started upon latest update, here is my solution.
- I was running a VPN, not sure this is part of the issue but disable it temporarily anyway if you are running one.
- In the search bar, type 'mail'. Right click on the app and click 'app settings'.
- Click 'terminate'.
- Open the mail app, then click sign in or whatever it says. After disabling my VPN, hitting terminate and reopening the app, I clicked sign in and up popped a request for my login pin. I added the pin and now am not being logged out.
I think you have to trigger the password/pin request or it will continually log you out. Initially this request was not appearing and I was having this issue.
Hope this helps someone, peace and love.
