Question Can I transfer app data to another phone?

[SGvagon]

Hello,

I am using Xperia Keyboard, but today when I installed it on new phone, the server with languages is maybe down :-/ . Can I somehow transfer downloaded languages to new phone? I can't find any folder with Xperia keyboard folder in internal storage. Thank you in advance.

I am trying backup this app from Xperia 5 III with Android 12 to Xperia 5 II with Android 11 .

I tried ADB command

adb backup -apk com.sonyericsson.textinput.uxp -f backup.ab

but it only saved 1 kb file and restoring it did nothing.

So maybe languages from Xperia Keyboard is in another folder?
