Hey there asfand258,
Thanks for reaching out to the Apple Support Communities. We'd be happy to get you pointed in the right direction for help with removing this information.
Based on the information you've provided, and steps you've gone through, the best option would be to reach out to the app developer directly for additional information and possible steps.
For help with reaching out to the app developer, check out this link here: How to contact an app developer - Apple Support
Contact the developer of an iOS, iPadOS, or watchOS app
1. Open the App Store on your iPhone, iPad, or iPod touch.
2. Search for the app, then tap it. If you can't find it, tap the account button
or your photo at the top of the screen, tap Purchased, tap "Not on this [device]," then tap the app.
3. The app's product page appears. Scroll to the Ratings & Reviews section, then tap App Support. If you don't see App Support, make sure that you're signed in with the correct Apple ID.
We hope that's able to help.
Take care!
