FB website exercise videos lags for 3 weeks now

Hi. I'm an FB Plus member. I'm wondering if anyone experiences videos lagging and would resume on the part as if it didn't lagged or stopped at all. So I would miss maybe 10 - 30 seconds of the exercise and would have to rewind the video again. I tried fitness blender's videos on Youtube and I don't experience this. I'm sure it's not my internet connection. I'd gladly exercise using FB Youtube but most videos I use is for an FB plus member so its not on Youtube. There was a maintenance in this site about a week or 2 ago, I thought it's gonna fix the buffering videos but it didn't. I hope this gets fixed. It's disrupting my workout most of the time now.

Am I the only one experiencing this?
