Hmm, what Android version do you have? I've tested it on Android 10 and 11 and it works, and most users are able to save/load. But I'm thinking maybe the latest version of Android has troubles with it, let me know the detail.
my phone is Android 13, i think that's why it's not working properly, thare's no "ok" button is showing , how am I supposed to save with lout a ok or enter button ?
