At Google, usually, they do things in a rather efficient and ergonomic way. But on the monitoring of subscribed channels, they
screwed up failed! It is almost impossible to know if there is a new video, only with the small numerical indicator present in the list of channels!

Result : Use RSS with YouTube
So the link of a YouTube channel is also the link to its RSS feed!
Little example: DATA GUEULE channel’s RSS feed:

After analysis, it appears that when the aggregator tries to retrieve the feed, it is (usually) automatically redirected to the real URL of the feed:
So in case of problems with the first URL format, go for the second one (or directly uses the latter).
