Can't open encrypted libraries - Android

Since last update of seafile for android, the client (version 2.2.6) can’t open encrypted libraries: when i enter the correct password and press OK nothing happens, the password box stays on top and no error messages are displayed.

Things don’t change decrypting data server side/locally.

My server is seafile 6.2.5, running on a Banana PI. All other clients, such as web, windows, mac, linux and cloud file browser can easely open encrypted libraries.

Android phone is Xiaomi Redmi Note 4 (Mido) with LineageOS 15.1 (Android 8.1). Never had any problems since now.

Any help? Is there a log I can see and post for debugging?

Just tried with another smartphone against same server, sam result. Is there a known bug?

Anyway, the problem disappeared after upgrading to 6.3.2 (done with issues, solved thaks to Internal Server Error after upgrade from 6.2.5 to 6.3.2 )
