gvprtskvni Though I use Freetube on desktop Linux and it tends to break occasionally, but it's usually fixed within a week or so. Maybe Newpipe is having similar issues.
I don't know what's wrong with Youtube.js's approach, but it constantly breaks every other week requiring an update to be functional again, when Newpipe extractor rarely ever breaks. Newpipe hasn't seen an update since July 31st, and the last time it's really broken was in May. Freetube has broken 4-5 times in that time period and required an update every time.
For OP I suggest subscribing to the Github repository for Newpipe so you get email notifications when new versions are available, in case it might just be that you're behind and need to update. There should already be a check in Newpipe to tell you about new versions, but that might not necessarily always work.
