YouTube preload

[Andeh13]

Can anyone explain to me how I can control this? I have turned it on on my android phone and it does seem to download 4-7 of my subscriptions, but it doesn't seem to do it in any logical way.

I watched 3 of them today, yet they are still "preloaded" - how do I remove them so more can be downloaded?

Two further subscriptions have released new content, yet this hasn't been preloaded. I have had wifi on all evening.

Is there any way to force YouTube to preload videos that I am not subscribed to?

My "watch later" videos are all very old, yet I can't remove them from the list on my mobile. Is this correct?

Can anyone offer any suggestions on the above?

Cheers

Click on a preloaded video in the lower right hand corner, about where the green arrow indicating that it has been preloaded is, and it will give you a remove option.
Once you have removed them it will preload others.
