Back in 2021, I purchased the All Puzzles Pack through Google Play, because the app is awesome.
I know that I can download the .apk to install J-crosswords from sites like uptodown and apkpure, and I'd rather use those sites to update my phone apps instead of Google Play if I can.
Can I:
Uninstall the copy of J-crosswords that I downloaded from Google Play
Install a copy of J-crosswords from uptodown.com
Apply my purchase of the All Puzzles Pack
If it is possible, how would I transfer the puzzle pack and audio clues in?
Unfortunately, I am not sure of a way to do that - I developed J-Crosswords a number of years ago, and both my time restraints as well as the low usage of that app makes it difficult to add additional functionality :(
