Chimes Update and Stop at 95% and Fail. Tried all I think

I read a string about Chimes and failing at 95% to connect and now when I search the forum actually errors....mmm. I have 3 (gen 2) chimes that have simply stopped working.  I have tried soo many times to reset and start again.  As per the forums I have created a separate SSID that is locked to 2.4GHZ specifically for the chimes.  Again after countless tries it still fails at 95%. I see this is a hot topic but with no real direction on a solution.  Just today my parents asked me to recommend a solution for there front door.  I actually suggested Arlo as Ring is not as reliable as I thought and its only going to cause me hassel tying to help them.
