MobileSheetsPro is going to still use the old cropping coordinates that were assigned if you replace the file, unless those cropping coordinates are detected as invalid after it checks for changes in the file. So the cropping may not match what you are looking for in all cases. It's not too difficult to reset the cropping for a collection of songs though - just add them all to a setlist, load that setlist, go into the cropping editor, tap Settings in the overflow menu, change it to crop "All songs in setlist" and then you can tap "CLEAR" to clear the cropping for all of the songs in the entire setlist. Alternatively, you can go to the overflow menu and tap "Auto-crop all pages"  and this would recalculate the cropping coordinates for every song in the setlist. If you add all of the songs in your library to one setlist (also easy to do, create a new setlist and in the group editor, tap the add all icon at the top right which looks like two arrows), you can auto-crop them all at once. So I don't think you need to delete and re-add all your files.

I did not think you were being rude - there are still plenty of areas for me to improve both the manual and the app. If a user encounters usability issues with the app, that means something in the design should be improved. It's sometimes difficult to find the right balance between having access to lots of things at once (i.e. icons that don't take up a lot of space) and having things be very accessible (i.e. names below icons, tooltips, contextual help, etc). I'll keep working to improve things over time as I can.
