As the title says, I am not able to play with 4K on Unitymedia/Vodafone in Germany. Internet speed test says that everything is fine (60 Mbit). Happens since yesterday, July 30th.
are you still experiencing these issues?
How did you managed to play in UHD before (Chromecast Ultra is a minimum, right) ?
Destiny 2 is, as far as I know, a 1080p game in Stadia.
Any further details on setting are helpful 😉
