Hi all on my 14 pro max I could click the play icon on the shark rf link and use my iPhone to openspot link ti speak on my iPhone over the open spot. Only the 4 pro does this. However since moving to the 15 pro max this function no longer works. App says can’t playback. All other functions work fine and I can see everything and link to the openspot 4pro. Just can’t use phone to talk over the openspot. One of the reasons I bought the pro version over the std openspot.
