Hey folks. Recently set up a new system, using a WiiM Ultra streaming to the WiiM-enabled Audio Pro A10s in three different rooms via Bluetooth. All speakers are grouped. Very pleased with overall functionality so far, but one annoyance has cropped up -- our WiFi is a bit spotty, and every time it drops, the group is lost and I have to re-group. Is there any way to set the grouped status as a default?
