I had since yesterday the same problem. I think it is connected with the browser agent used to connect to Tidal login page: infact I used windows PC, with Edge default browser to setup my roon settings and I noticed that the Tidal login page is unresponsive when I use Edge. I have just solved this issue using the Roon App on my iPhone to connect to Tidal. Probably it shoul work also simply using another default browser on the tidal control app, but I didn’t try it. Hope it works also for you.
