For anybody having trouble with K-9 Mail and Thunderbird being in the same Release section, add this to Filter APKs by Regular Expression:

To get only Thunderbird Updates: ^thunderbird-.*.apk$

To get only K-9 Mail Updates: ^k9-.*.apk$

It works with Graphene now.

I dont really have a favorite. I use the Google Camera because of the Quality but without the Internet Permission. For quick pictures i use the Graphene OS Camera App. The Graphene OS gets actually better day by day so i might uninstall GoogleCamera soon.

Host your own and only get a few friends or family on board to mask your traffic.

I tried calling the support today but i did not get to anyone. I will try again later. If i cant contact support i will probably send it back.
