@kperakak you need a token for tidal app for android. I don't know why, but if you use the token of windows tidal app cause the encrypted error. So,

1. Install BlueStacks (an android emulator for windows, so if you have other OS search other)
2. Install an old version of Tidal, i.e. 2.37 (https://www.apkmirror.com/apk/tidal/tidal-tidal/tidal-tidal-2-37-0-release/tidal-music-hifi-songs-playlists-videos-2-37-0-android-apk-download/)
3. Open Tidal App and do login
4. Finally, go to /Android/data/com.aspiro.tidal/cache/okhttp folder, and search in all files "X-Tidal-Token", in my case the file contains

https://api.tidal.com/v1/pages/home?deviceType=TABLET&locale=es_ES&countryCode=ES
GET
2
X-Tidal-Token: {TOKEN_HERE}
Authorization: Bearer eyJraW.......

5. If you have already Strawberry Music, uninstall it and install again.
6. Go to 'Tools -> Configuration -> Tidal'
7. Check 'Enable' and check 'Use OAuth'
8. Put the token in 'Client ID'
9. Click on 'Access'
10. A browser will be open, put your credentials and after that appear an alert with a button to return to Strawberry Music.
