I was on beta but left the programme but left the group but still got no control is there any step by step things I could try ?

You may not have successfully left the beta program, at least in terms of software. You should check your systems and make sure that both speakers and app are on rev 6.4.x



Please note that there are significant issues with leaving the current beta program, as listed in this thread:
