I've had a playbar and sub for a couple years for our main TV, just picked up a pair of play 1s to complete the system. After adding, during trueplay tuning, it keeps telling me I've lost a speaker. No issues at all during the sitting portion, but gets about 1/3 through the timer on the walking portion and gives me this error repeatedly. I hear all the speakers playing the sound. I've rebooted my router and the speakers, no improvement. Very frustrating after a new purchase, looks like a common issue but I haven't found a solution searching. Submitted diagnostics, number 2029678020. Please advise.
