Hi, i upgraded yesterday to K9 and i have a permanent @ notification in the navbar.
The real problem is K9 is now totally draining my battery.
Anyone aware of this / experience this issue ?
Thank you
What K-9 Mail version did you run before the upgrade?
The “@” notification is displayed when at least one account is configured for Push. See How to configure Push?
Hello,
I’m not sure what version it was, but i update K9 via F-droid and in a pretty regular way.
For now i’m back to previous one in f-droid (5.734) with export from 5.737 and import in 5.734.
I believe this could be related to push, so if i can help you, either with Logcat or whatever… (Android POSP 11 custom ROM on Nokia 6.1 plus).
Kudos for K9 ! 
Yea, Push drains battery because the device never sleeps when it’s enabled - I mentioned that a week or so ago. That’s why I’ve disabled Push again for now and am hoping for a fix in the future 
I have the same problem with K9 5.739. The battery consumption is catastrophic.
