Powered by Median banner appears despite buying Starter plan

I purchased the Starter plan which says it removes the "powered by median" banner on start-up.

At the moment I registered my iPhone as a iOS tester and downloaded my app for testing using the QR code under Build.

It is not in the app store, not have I started the process of publishing to the App Store.

The app I have on my phone is the one for testing.

Will this "powered by median" banner on start-up be removed in the real published app?
