Hello iostrym, unfortunately it has been silent for some time now. What I did is download the v5.3.24 apk file (from a reliable source) and disable auto-update of the app. This version does not have this problem.

Really hope support is picked up again. Actually hoping for some nice new features as I still fully believe in F-Stop. I have moved on to a new tablet and use it even more now. In fact one of the reasons to buy an android tablet versus an apple one is the very existance of F-Stop! In my research I was unable to find anything close to F-Stop on iOs.
