Some workmate come to up with a issue on mutiple videos
should find the video like the web version of youtube
can not find video
I am unable to reproduce it. This video and a newer one are found. I guess this one could be solved by the feature request of issue #3329
The pull to refresh should also be added in the ChannelFragment
can not find video
You'll need to be more specific. If there is a toast, what does the toast say? If there is an error, paste the log.
I can give you a screenshot:

Have you enabled "YouTube restricted mode"? If so, disable that.
@wb9688 works now, what is that option for ?
