### 1/5 — What is the purpose of this application?

*2024-11-25*

I installed this app earlier and acquired a monthly subscription. However, upon reviewing the app's description, it indicates that it is a location changer, which does not appear to be functioning. There seems to be no operational feature in this app. I am puzzled as to why Apple would permit such an app. Kindly address this issue promptly or reimburse my payment. The consistently misleading practices by app developers on Apple's platform are disappointing. Your urgent attention to this matter is appreciated. Thank you.
