I just uploaded a new version of Friendiqa to my private Fdroid repo at https://www.ma-nic.de/fdroid/repo
and to the Playstore at https://play.google.com/store/apps/details?id=org.qtproject.friendiqa.
Most important changes is the ability to follow/unfollow contacts isnide the app due to the new APIs in Friendica 2021.07.
Unfortunately I had to hand over my signing key to Google due to the new App Bundle requirement in the Playstore. In theory Google can now install a changed version on your device without you knowing from the changed signing key.
The version in the Fdroid has the same signing key.
