Youtube's ToS do not allow to download their content directly under the threat of a ban. However there could be a workaround. There's an excellent app out there called the NewPipe. It allows to download the YT videos (and even the extracted audio) through the "Share" button on YT itself. My request is to integrate the option to "Share" the YT videos in RSS subscriptions of PA to NewPipe if such app is present on one's device.
