Hi there,
I installed Liftoff this morning on a super old Android Device (Android 8.1) via Google Play without any issues.
So next step was to get it on my Smartphone running Lineage OS with Android 13. I was not able to find it in the Play Store, so I used the Link on the Github site of #liftoff and then Google Play tells me that this app is currently not available. OK, next step is F-Droid... can't find it there at all.
The Screenshots in Google Play look like they were created on a Smartphone, so my problem should not be Tablet vs Smartphone, but something else, right?
Edit: Forget about my question for F-Droid, I just read that it is not there, but the issue with Google Play still exists :-(
