Same issue here. Our Advanced App Clip Experiences are stuck in "Received" status for over 2 weeks now. Funny thing is, one of them used to be live (can't remember what the status used to say). It was working until we decided to edit 2 words in the tagline of the Advanced App Clip Experience - then it went to "Received" and has never changed! We've submitted 2 app updates since then, both of which were approved and moved to Ready for Sale, but the AACEs stayed in "Received". We're currently on our 4th person from Apple Dev Support/App Store Support. Can anyone help? We're supposed to demo this on stage at a dev conference in a few days.
