I submitted an app and it was rejected with what looked like a generic message that said "We noticed your app shares a similar binary, metadata, and/or concept as apps submitted to the App Store by other developers, with only minor differences." I'm new to app development and this is my first app. Prior to starting, I searched the app store for the functionality and didn't find anything similar. So, I created a unique app using the online Thunkable program. I responded to the rejection message with this information and asked for clarification. It's been 6 days and Apple hasn't responded to my request response. I put in a lot of time and effort developing the app and it very frustrating to have this held up. I'm looking for suggestions on how to proceed.
