All I see is the words "IGNITE TV" and the 3 loading dots on a black background.
I have tried Chrome and Edge with exact same results.
It keeps trying to cycle between the login page and this Rogers page: https://www.rogers.com/web/ignitetv/signin?scheme=oidc&action=display&sessionID=ac17c641-9784-4987-b...
@mgpierog I don't have any problems using ignitetv.rogers.com with Windows 11 either. Works fine for me with Vivaldi (Stable and Snapshot builds) and Edge.
I once experienced a similar issue as you while trying to connect on Win10. I cleared my browsing data, relaunched the browser and everything worked fine after that. I could also see a similar problem occurring with some security/privacy browser extensions active. (However, I can also confirm that I don't have any problems with uBlock Origin with the default filters active.)
