Hi AfriMan
Yes... this is exactly my current experience.
It used to play on medium without buffering... but since late Saturday afternoon I cannot watch a Twitch live stream on medium without it buffering on the business account. It buffers 20 to 30 seconds into the stream and then every 20s to 30s it buffers, for as long as the stream is watched, be it 5 minutes, 10 or 20 minutes... constant buffering. It happens every time I load any stream, at any time of day or night.
The free 1GB account is buffer free on medium. Here any live stream loads on medium and will stream free of buffering until the stream is finished or the browser closed.
The business account used to be just the same.
The constant buffering makes watching the stream impossible... so testing it is limited by the irritation threshold which is reached rather quickly, alas.
This appears isolated to Twitch only on the business account, everything else on it is working just fine here.
It is puzzling as to why this has happened almost overnight.
We'll need to run some tests on our side. Could you please PM me with the link to the stream you're watching and I'll check it out on a test account?
