I’ ve disabled “Enable MPD album art” and enabled “Enable MPD embedded album art” in Album Art settings.
This worked perfectly for me up to MAFA 1.8.3, but in 1.8.4 no album art is shown.
Also after clearing the cached images, the Number of images stays at 0.
MAFA version: 1.8.4
Android version: 7.0
Device model: Huawei MediaPad T3
MPD version: git master
