HiFi Rose RS130 RoseTube has stopped playing videos in 4K as of today. There has been no recent firmware update or settings change on my side. My internet connection is 1Gbps, using wireless, and I have no internet issues with other devices or services.
RoseTube videos now appear to play only at a lower resolution, and I cannot force or select 4K playback. Please advise whether there is a known RoseTube service issue, a server-side change, or any setting I should check on the RS130.
Thank you!
