1. I had set it to skip 30 seconds, and it (out of nowhere) stopped working - it now skips 5 minutes, which isn't good at all.
2. Volume controls no longer works.
update: fixed the problem.
had to resync the volume control. and for the skip:
simply re-doing the code to set it up (exit exit exit 0030) wasn't working, but I found (for future reference to anyone encountering this issue) somewhere that pressing exit exit exit 0500 followed by exit exit exit 0030 fixed the problem, and it did for me.
