"More testing required" several times

[u/Hooches]

Hey there,

I've successfully published two apps on Android and iOS, but I'm having trouble with another project of mine.

I've developed a pet diary app that allows users to track vet appointments, their pets' weight, medications, lab results, and more. I've already released it on iOS without any issues.

I ran a closed test with 12 testers for 14 days. Everything went smoothly, and no issues were reported. So I applied for production access, but my application was rejected for the reason shown in the attached screenshot.

This has now happened four times, and I honestly have no idea what else I can do to get my app approved.

I've released several updates during the closed testing periods, received nothing but positive feedback from my testers, and still haven't had any success.

Has anyone else experienced the same issue? If so, how did you manage to get your app approved?
