I experienced this yesterday a couple of times. I assume the latest app update included changes to the refresh during orientation changes to the device and for Wi-Fi hops of the device. That is purely speculative on my part. I have a Wi-Fi mesh setup, which is why I think that may be the case or at least has something to do with it.
A purge of the app cache tended to fix it. I was also experiencing internet provider issues last night and reset my network a few times to work out some stuff. But that’s my edge case…
Same here, clearing app cache doesn’t fix anything for me and its really annoying when viewing a video feed in landscape and having it reload each time I change orientations
