Same situation here, with a slightly different twist. Timeline (KST): Sep 28: submitted an update to an existing live app Sep 30: rejected under Guideline 2.3.1(a) (metadata). Fixed the same day and resubmitted with an expedited review request. Sep 30 – Oct 7: "Waiting for Review" Oct 7: changed to "In Review" and stayed there for 3 weeks with no activity on the demo account provided in the review notes Oct 16: App Review Board replied to my appeal that the 2.3.1 issue was no longer valid and sent the app back to App Review Oct 28: cancelled and resubmitted. Now "Waiting for Review" again. Developer Support confirmed the "In Review" status and said the review should begin shortly, but there has been no progress. Support replies took about 9 days. Other apps under the same account were reviewed within hours during this period, so it doesn't look like an account-level issue. Has anyone seen a submission stay "In Review" this long, and did cancelling and resubmitting help?
