Need a fix on a mobile app

I had a developer add a feature to my app. It was originally two button that can only be accessed by keys, and each key lasted two weeks. I had it updated to be coded to work with discord authentication so that it would require login to their discord account and it would view if they had a specific rank in my server and give them access based off that. Problem is, it’s not working too well. Need someone to fix this for me asap, meaning today, and upload to TestFlight for me. It is coded in React Native.

In order to win this job you MUST understand discord. You must say “I understand discord” in order to win.
