Magnifi Mini occasionally does not work. Forced to unplug / plug in power cable.

I woke up this morning to see the amber power light on. My tv was off. I currently have optical and ARC connections to the bar with ARC chosen as the primary source. I chose it days ago using the remote. I turned on my tv. No sound. Light was still on. This has happened before and each time I'm forced to unplug the power cable and reinsert it to get the unit to function. When the bar is frozen like this no buttons work on anything not even the power button on the bar. What could be the issue? I've thought about using optical only to see if the bar freezes again. Maybe the HDMI ARC is faulty. The tv is an old Sony Bravia. The connection on the tv does say ARC.
I previously owned a bose solo 5 with no problems whatsoever but I wanted a compact bar with a subwoofer and believed polk to be among the best audio companies.
I've had my mini about a week. I have a month to take it back for whatever reason and that's something I've considered doing given my experience with the sound bar and customer service. Calling them resulted in almost two hours of being transferred to someone else. Nobody was able to deal with a firmware update apparently and at the time I couldn't connect the bar to my wi-fi for whatever reason. The google app didn't find it. The bar also froze for the first time that day. I got tired of the runaround. I hung up. I sent an email to customer service and never got a reply.
I finally connected the unit to my wi-fi network through google home. The app shows the firmware version to be 20. I guess that is the latest version.

I did receive an email from support on the 15th. I sent my initial email on the 8th.
If you can wait a short while, let me have someone from Polk contact you via email?
