I know there is a paid app on Playstore that apparently works. Don’t remember the name. Will have to look it up. I came across it during my research. But there is also this on GitHub: https://github.com/residentsummer/watoi
This is Android to IOS i was think of IOS to Android. Btw i was wondering why do the paid apps charge so much for this transfer. But thanks to you now i know this stuff is complicated and you have done an amazing work decoding it.
What if now the next post about how to import this to Android?
Then a program which is open source project for this purpose? But Only if you have time!
Give it a try and see how it goes?
