Welcome to the forum.
Specifically, this app is available in the same locations as another identical app you submitted to the App Store.
That's whet the reviewer has detected (and may be several reviewers as you explain that this lasts for 5 months). Is it the case ? Do you see what is the other app the reviewer has in mind ?
i have made a lot of changes but still getting me that.
What type of changes ? If it is only the look but the functionality and content are very similar, that will not solve the issue.
If the changes are significant, then you should clearly and convincingly explain it in the comments to reviewer in the Appstore Connect submission form. It is then a good practice to explain also in the other app, next time you will update it.
i have had appeal and submit evidence that my app is unique but still not.
Is it unique or does it have unique features compared to the other app ? It is crucial to be clear and straightforward when giving information to reviewers and not pretend what would obviously not be the case (app uniqueness)
