The error is not fixed with the 5.9 update either.
Reproducible error is detailed here: RoseTube not playing videos that are live on YouTube - #6 by taystnotes
Current workaround: Turn the 150b off for 1 hour. Power back on and RoseTube searches/plays work.
Rose tube stops every time I use it after 1-3 hours of playing on my 5 months new RS 130.
Bin like this from first day 
Som wan find the solution yet?
I tried the new 5.9.2 and it’s still not working like it supposed.

I checked the video you sent me.
I forwarded the video to the software team.
They said they will fix the issue and release an update as soon as possible.
@ROSEHAN on behalf of all users who are troubled by this reproducible problem, thank you for taking the necessary steps to fix them.
I am having the same issue and I have reinstalled/uninstalled a bunch of times, that never helps
Same here…. Install/reinstall - no changes. Videos are Not possible
Very frustrating for machine that cost 5 times more than a wimm ultra that i owned
Just tried to play rose video all my saved . Nothing plays. I get the same error. Frustrating.
Dear HiFi Rose users
ROSETube playback was temporarily unavailable yesterday.
The issue has now been resolved, and playback should work normally.
Please refer to the link below for details:
I have been experiencing this issue. I get a few hours (maybe) of Rose Tube playback. Then the dreaded “Temporary playback issue. Please try again later.” I’ve shut down the device (RS250A) and have reinstalled the RoseTube app. Currently doing the “try again later” wait. Has anyone else had success reinstalling the app? Has this been fixed?
Please check a few things for us:
