I always like to review the changelog after I update the app.
An issue I keep coming across is I can only scroll "down" the change log. If I try and scroll back "up" it closes the "what's new" tab. If I open the section again it remains at the point I left off and I can't see the top of the change log unless I force close the app.
The 3rd party software used to show the changelog wasn't written to allow that scrolling and the developer isn't updating it either. I haven't found a replacement yet so it's just something to live with for now.
