I'm on 1.20.1rc2 on firmware, 1.20+1 for wifi server and, 1.20 rc3 on dwc version. I have set macros up now so I can just use the panel due to reset the wifi turning off then on, I have been speaking to doug and he said to try rolling back to 1.20 on wifi server and try that. Will let ya know how it goes..
There is also another chap on our discord channel that has had the same issues after upgrading his firmware from 1.19 to the 1.20+1 too
