It is an ipad mini 4 so maybe it's getting a bit old.I wouldn't think that would affect what trueplay does.I think it's maybe a speaker fault or it's just the way trueplay has set up for the room.Thanks
As the 5-pair work without Trueplay, the worst case scenario is a ‘fixable’ software issue, in which case I think we would have seen more reports in the community here about the issue. If a reset doesn’t sort it, my thoughts are to certainly try another iDevice and re-Trueplay tune the room - I’m assuming though that your listening environment is not in anyway unique, or so unusual, to likely cause such strange tuning issues. Anyhow hope you get it resolved and that you will kindly report back the outcome here.👍
