By default, the check mark is Use NNUE - the network will play, if you want, you can disable this option, then the usual Stockfish will play.

In the video, I showed you how to install the network that you want, and not the network that is built in by default.

In fact, the default network is already inside the engine. If you want to play this network, just download and upload to droidfish., without specifying the path.
