@hopeless I had the same issue of buffering every XX minutes and fixed it. As suggested by the admin below, email the team for any issue but it's most likely an antivirus scanning chrome and causing buffering. In my case it was AVG, I re-configured it liked highlighted on the page below and restarted chrome (chrome://restart or you can restart PC). After that AVG is still protecting my PC and the videos dont buffer anymore so it worked. Thanks VS for a great product (just sad this issue is not handled in the software/setup).
Cheers,
