I download few YouTube videos using **YouTube Offline** feature introduced recently in an Official YouTube App.

Those videos were accessible to me and I played them successfully, without any issue.

Because of some device issue, I happened to "uninstall updates" of YouTube App. 
and now I had an old version of YouTube.

I then took the update of YouTube app as I wanted to enjoy the new Offline feature from Google Play store, which had the Offline feature.

But when I went to "Offline" tab in my YouTube App's Navigation Drawer (**After Update**), I could not see my previously downloaded videos.

Of course, I used same Google Account for my YouTube Sign-in.

So, let me just re-phrase the issue:

**Whenever YouTube App's Updates are uninstalled, all offline Videos too are removed.**

And when I update YouTube app later(which has Offline feature), App does not contain previously downloaded videos!

Any ideas, how can I get my lost videos??
