Same thing for me!
8 / 10 times it just does not load subtitles (en).

I would like to see Addic7ed support for subtitles too. :)

I see premium features in Chrome but on Android I don't see anything new.
I should see at least playlist feature.

Am I doing something wrong?
Android app does not ask to sign in with a specific Google account.
I have 3 google accounts on my mobile.
Is that a problem?

Battery drain is significant. Nearly 50% other day went at nothing!
