Videos not activate the download button

I used the app before and was working very good in downloading videos from the channel and also playlists, lately it not downloading videos directly from the channel, when I add the link of the channel like https://www.youtube.com/xxxxxxxx/videos or https://www.youtube.com/@xxxxxxxxx/videos (while xxx represent the channel name) the app not activate the download button to start it

Does it happen on all channels or a specific one?

all the channels which I tried (if I tried to download all the videos) but from the same channels I can download the playlists
