NiLuJe, the issue remains. I think my mistake, must have used the old version and not the most recent
So anything after 2018-08-07 for Android 4.2.2 is crashing. Tested with the Onyx Boox firmware too, still the same.
Also I noticed that in history it doesn't parse new entries, so it can't display covers if not already there. And of course if attempt to open any epub then it crashes.
