Waiting for Review for 15 days - first app back in the queue after a sandbox issue

Hello,

Our first app, Bookella: Book Tracker & Log (Apple ID 6804023709), has been waiting for review since October 14. It was reviewed once, but the review ended early because of a temporary StoreKit sandbox error, and the app went back to the end of the queue. Timeline:

Oct 14 - submitted version 1.0.14
Oct 22 - expedited review requested and accepted
Oct 28 - reviewed and returned under Guideline 2.1(b) because of a StoreKit sandbox error
Oct 28 - resubmitted as 1.0.15, back in Waiting for Review
Oct 29 - expedited review requested again and accepted

According to our logs, the review lasted about 5 minutes. The plans loaded, and the App Store payment sheet opened. Then the sandbox returned a "store problem" error, and the products stopped loading. Purchases work correctly in our own sandbox and TestFlight testing. Version 1.0.15 also retries loading the plans automatically.

We have now been waiting for over two weeks, and the first launch is still on hold. Could someone from App Review please look at our submission?

Submission ID: 47af8ce4-c8ea-457a-af1b-32e122fe8e02

Thank you!
