App in review for 3 weeks

Hi, ive submitted an app 3 weeks ago, after the first day a video of the apps flow was requested, since then its been 3 weeks and no reviews, ive also made changes and submitted newer versions and no updates from app review. Ive sent support emails and expedited with 0 feedback. Please can someone help?

Good Luck! Im waiting september for over three weeks for only one build. Now waiting since 15 october, no answer from apple after several support tickets.
