For a few days now the DeoVR browser on my quest has been completely unable to render any pages that do not support the tiled view. I've spent a bit of time on the forums looking at similar discussions and tried everything I've found - reinstalling the app, quitting while in the tile view (e.g. deovr.com) and then restarting, power cycling, even going into the app files with Sidequest and manually deleting everything in the cache directory out of desperation.
Example pages include google/amazon/bing but literally nothing I have tried will load properly. Sometimes the same URL will give me a black screen; sometimes it will give me a white screen; sometimes there will be a scroll bar and sometimes there won't. Occasionally - not every time - entering and attempting to load a new URL will result in a static image of the previous website I tried to visit: for example, I just tried visiting google.com (white screen) and then went to amazon.com and I was presented with a static (uninteractable) view of the google landing page.
Deleting the cache files "helped" in that I was able to initially interact with a page, but as soon as I clicked a URL it went right back to not working.
Edit: I have also tried both the Oculus app store and Sidequest versions of the app. Both show the same behaviour.
