If you're having trouble with your Twitch watch time not being detected, here is a workaround that works perfectly for me:
I run 4 to 6 streams simultaneously. If the tracker fails on one, it usually catches another, so the count goes up much faster.
Important tip: They will auto-pause if covered by another window. My solution is to let the tracker connect, then squish all the streams into tiny windows and stack them on the side of my screen so nothing overlaps them.
