App stuck in “In Review” for several days

Hello,

My iOS App (Apple ID 6811252087)update fixes a serious bug and has remained In Review for several days, even though an expedited-review request was accepted.

I understand that the review may take a long time, but I really don't understand why the app has already been in the "In Review" status for several days and there is still no result.

An earlier submission also stayed in review for a long time, so I withdrew and resubmitted it. The overall process has now taken more than a week. Developer Support says the review is ongoing but cannot provide a completion estimate.

Is there anything else I should check or provide while keeping the current submission active? Have other developers experienced similar delays recently?

Thank you.
