Directly after updating, I am observing the issue that the connectivity check fails in all WiFi networks. I also have general DNS issues in apps like FediLab and Spotify, while opening the same pages in Firefox works.
There seems to be symptomatic overlap with No wifi connection on OnePlus 9 Pro although wifi works on another phone and Captiveportal.kuketz.de DNSSEC issues again - #4 by rik
I have forced the system to use the WiFi Network by disabling cellular data and despite the connectivity check failing, internet works. The connectivity check also does not fail on cellular data alone - which I consider to be quite odd.
Will update when (or if) I have more info on this. Just putting it out here in case someone is wondering why their WiFi doesn’t work.
