incompatible versions
ApkTrack currently shows a wrong version as current, if there is a newer one, that is not compatible. This is at least the case for F-Droid.
To reproduce you can install Jamendo from F-Droid on Android version newer than 2.2.
There is a newer version only available for devices with Android up to 2.2, that is shown by ApkTrack as current, also on newer (and incompatible) versions.
Ah, it is true that ApkTrack makes no distinction between compatible or incompatible versions. I'll have to work on this at some point.
If there would be a reference/variable in the versioncheck regex it could be updated to choose a compatible version
But we have to split this as on repo page the compatibility and on wiki (or in metadata file) the current version can be found.
