Official tutorial videos are stalling

Hi Agent,

I got 200M network with max 25Mbps/s download speed in China, I’m able to watch any 1440p videos on YouTube with no problem. But, I can’t even watch official tutorial videos on 720p, videos are always breaking up and I have to pause for a while to let it load.

I can’t always decrease the resolutions, otherwise I can’t see clearly which section the teacher is pointing out. Is there any way I can fix the connection issue with official learning studio?
