Are you using 2,4G or 5G WiFi? 2,4G is usually very hit and miss depending on your location, and not really great for streaming.
But I have to say the app does severely slow down the connection speed for some reason. I have a 300MBit connection to my ISP, when I do the speedtest on the site on a Desktop Browser as well as on the Browser of the Quest 2 (when running with 5GHz Wifi) maxes this out. But the speedtest in the App is always severely slower, usually in the 50-100MBit/s range, which still is plenty enough for streaming, but weird.
Also in the past the CDN sometimes got quite confused for some reason. I live in Europe and for some reason it sometimes connected to servers in the US which obviously leads to pretty bad experiences, but I did not see this recently. I sometimes miss the old times where you could manually select the server you want to use instead of relying on a CDN to do it, which sometimes very obviously does not take the optimal source (not just related to slr, but pretty much any site that uses CDN)
