Persistent getting 429 Errors, Even With No Activity on store

I’m getting the 429 “Exceeded 2 calls per second for API client. Reduce request rates to resume uninterrupted service” error, even with no activity on the store or app. I waited an hour and one day.

My App is a public app that uses REST API like ORDER and PRODUCT one of my app users is facing this issue. We are also waiting for 2 seconds (Also tried for 10-20 secs) for any request but only for this store user, I am continuously getting the same error even with no activity on the store or app. I waited an hour and one day but the response is still 429.

Below is my response :
