Hello.
From yesterday, I’m noticing similar troubles with endpoint https://api.twitch.tv/helix/users (view_count). It is not updating views of the user’s channel. I get this data at the beginning of streams and at the end and value is the same after several hours .
This problem could be checked in popular pages like “twitch tracker” or “streams charts”. Example:
https://twitchtracker.com/auronplay/streams/45255402028 (views gained = 0)
https://streamscharts.com/channels/auronplay/streams/45255402028 (live views = 0)
Best regards.
