Videos are taking 30 seconds to one minute to start playing. Once playing they run fine.

When it started kept getting this video is unavailable. Now the circle goes round, then disappears and then starts going around again. Can happen up to 10 times before video starts. Last video started playing took over a minute to start playing.
