I resubmitted again and was denied again for the same reason. As soon as I received the notification, I went to my own channel page and discovered that all of my extensions were showing blank pages now, including the fully released ones that I did not make. I’ve included a screenshot of what Stream Legends looks like for me right now.
At this point, I am convinced that whatever is going on as part of the review process is literally breaking every extension on my page - even the fully released ones.
I think it’s time to take a break from experimenting with these extensions, at least until some issues in the process are ironed out. This is extremely frustrating and the feedback loop is just not good enough.
