My offline image function worked ok till April 2021. After that it would show up if I refreshed the page a few times but now it does not appear at all.
All I get is a message saying my channel is off line and click here to learn more about the channel ( brings me to a twitch.tv hosted page of my site)
To see , check here tvctk ( the text is in French)
I validated that the size of my image meets requirements . The embed code seems OK because I can stream live video on it.
Has the offline image feature been disabled
