Ninb I just created a video to explain the process. Hopefully, it will help!
wynnthorn hopefully, this video will help you enter the beta!
Favor even though I already have access, I decided to go through the process of joining the beta from the tweet. It did work for me, so I created a video demonstrating. I hope that it didn't only work for me because of my previous access. However, I believe this can be marked as a resolved bug. Thanks.
