I can confirm the bug. HUAWEI P30 Pro (Android 10)
Open MMA 1.4.3.946
Open a playlist/tracks/Album - press a song once
NowPlaying opens and the song is played
Shuffle / Repeat: tried all variants
If I press >> nothing happens
If I press >> twice, the next song will be played
From now on I have to press >> twice to play the next song
I also tried different playback options. Didn't help.
Equalizer: disabled/enabled. Didn't help.
