Hello. I recently purchased two One SL speakers. They worked great for about a month or so and now one of them works great but if I try to use them both…… it shuts the music on them both off. if I try to use the one in my kitchen solo, works just fine  if I try to use the one in my office, it shuts the music off. so that one seems to be the issue. I can’t figure out what to trouble shoot at this point
