Hi, I've got the exact same problem here, using Crosscall phone runing Android 6.0.1. The three golden dots above the chess board keep turning, and my move is not registered. When I play from desktop however, the move is well registered on the app, as well as chats or opponent moves.
No problems with lichess TV or puzzles either.
Uninstall - reinstall app does not change anything, as well of course as rebooting the phone. This happened with the "before-last" update, hasn't been solved by the last one.
Any idea ?
