We have the same problem.
On 11/03/2022, our app was sent for review.
The application is in the "Under review" status from 11/03/2022 to the present day (07/12/2022). It's over four weeks.
We wrote to support, but they answered us:
"When your app’s review is complete, you will be notified by email"
We made new builds and uploaded them, removed the application from the test, resubmitted it for review - nothing helps!
What else can we do?
