I've had the same problem for a very long time. This bothers me a lot. I couldn't even look at my Instagram stories because this problem persists. I'm an Instagram influencer, and I was used to posting many Instagram stories with music, and I couldn't even see the result because while I was checking my Instagram stories, the music stopped. I also asked for help from my Instagram followers - I gathered them with the help of 1394TA, but no one could help me. But fortunately, the problem is gone, and everything has been fine for some time. I hope this problem doesn't come up again.
