Hello team,
I have the same problem. Today I bought the R-41PM today 05.06.2021 and when connected by bluetooth it reproduces the music well. but when changing the album the player shows that the music is progressing, however the speaker does not reproduce the sound. I called apple support and they told me that it is probably an incompatibility between apple music and bluetooth. This problem does NOT happen on Spotify. test with 3 different Iphone and the symptom is the same.
Check if there is a firmware available for this speaker model and it is not listed.
