OK. Let's start from the beginning:
- Change your project name to: MAGreeky(.aia)
(→ packageName:appinventor.ai_<yourEmail>.MAGreeky), see also here. - Build the AAB on the test server
- Create a new app in the Play Developer console
- Upload the AAB (
MAGreeky.aab) to the Play Developer console
as an internal test track (→ internal testing).
