Real Debrid buffering

Has anybody had trouble with buffering using real Debrid . I use cinema he and cyberflix,and have countless problems with buffering.

I have to say in the last couple of months I have experienced a few links that have buffered. Never before had I experienced this. I think that their servers are being overwhelmed.
I usually just find another link and that resolves it. BTW, I only use Xanax build.
