For Authorizing Instagram with my App, I have followed
https://developers.facebook.com/docs/instagram-basic-display-api/getting-started
For deauthorization Instagram from the App, deauthorization callback
The issue I am facing is that I am getting different User Ids for same Instagram account upon deauthorize callback. When a Instagram user remove my client app from their account then Instagram sent a signed_request through the deauthorize callback url. After parsing the signed_request. We are getting different user id against that user!!!
Note: I am using a tester user for my client app
