I experience an issue connecting my Marshall Major IV headphones to my FP5 via bluetooth. Sometimes it works fine and connects automatically (as it should) within seconds as soon as the headphones are turned on. Sometimes it doesn’t though and I can also not get it to connect manually - as if the phone couldn’t “see” the headphones.
Also, whether I connect successfully at first try or whether these issues show up, the first few seconds of spotify sounds aren’t played via headphones. Sometimes it helps to pause/restart said spotify sound, sometimes it helps to change the volume - sometimes it doesn’t though. The sounds start playing automatically after a minute or so (not at the start though but in the middle of a song e.g.).
