Feature Description

The RSS feeds for YouTube channels seems to be leading to a 404 sometimes(it seems to work on and off in the past few days). So, Dedicated feed update does not fetch results at those times.

Not excatly sure if it is more or less than 10%, but assuming that people may have turned on dedicated feed update as it was faster.

Requesting that the regular feed update be set as an automatic fallback, so that the update happens without having to change the feed setting.
