I am using the e/ mail app for a work account and BlueMail for personal (eCloud).
i am now getting notifications from both apps for my e/ account. I cant work out how to remove it from just this app. I only have the option to remove it from my device.
perhaps worth noting is that i do not believe this was happening after i set up BlueMail.
At this point, it may be simpler to stop Mail app synchronization
To do this : from Mail start screen, 3-dot menu, Settings, Network, and set “Background sync” to “Never”.
