Youtube stops after five or six videos

[vosg]

After the update to lollipop, my YouTube app stops working and pops up "an error has occurred while playing, click to retry". There's no way to get it working again, only a reboot will work, but then after a few videos, the problem is back.

I've done a factory reset and tried without installing any 3rd party apps, same thing.

Anybody experienced the same thing?
