So I use Tutanota app on my Android phone and have the credentials saved for my main account.
The other day I logged in to check on a second account and after that logged tout, but I still keep receiving notifications for this logged out account, and it's fucking annoying.
@retiolus It's on purpose so that you also get notifications when not logged in. You can manage this under Settings - Email - Notifications and stop notifications for this device again.
