How to get out of Open Beta?

I am currently in the Open Beta and I know that the 20.3 release is coming today. How do I get out of Open Beta? Please let me know!

All you have to do is download the new updated IF and it takes you out.

However if you want the build to disappear from TestFlight, tap on the app and click stop testing


Just go onto your App Store and reinstall Infinite Flight.
