7.0 firmware has bricked my 2 Polk SB1+ sound bars - neither are usable – Play-Fi Review

I have been using Play-Fi products for at least 5 years. I have 6 Polk Play-fi speakers and they have all worked great until the recent firmware update required by the 7.0 iPhone app. After running the corresponding firmware update and my two Polk SB1+ sound bars are bricked and unusable. Both unit are continuously in a reboot cycle; sound bar turns on, does some sort of boot up, then becomes unresponsive after about a minute, then turns off and reboots. There is no way, to my knowledge, to stop this cycle. There seems to be a big problem with the latest firmware update. This is very frustrating. One of these units were paired with 2 surround speakers in my entertainment room. I’m very upset.
