hi! please make a bug report on github https://github.com/code-charity/youtube/issues/new?assignees=&labels=Bug thank you!
(btw reviews are not supposed to be about a bug(, which might only happen to few people or because of a YouTube update.) This is one of the 3 reason here allowing to flag/remove them. To make it harder our project is an uphill race against this since 11 years and work never ends. There are few extensions as ambitious as this and actually it would deserve 10 stars. (If you expect a majority of features to work for you, then you are expecting more work and more reliability already than most 5-star extensions provide to their single purposes. Yet they are what the rating systems will thus prefer. ) We currently might aim at ~95% of the stuff working for you costing most of our free time. And if we ever get funded might finally hire people and develop even several times faster.)
