I have the premium subscription, I am signed in and I wanted to use animate with audio feature, as it was working yesterday and it's just giving me a white screen with an "X" in the corner.
There are many threads on this same issue for what seems to be the last 24 hours. Sadly, Adobe has failed to respond here or on Twitter, and the status page falsely claims that Adobe Express is working. If you use Twitter (X) you might want to post to @AdobeCare to let them know and the public that their services are not working.
