How do you test an aab file? Seems the generated aab not taking from latest changes when downloaded

Im creating newer versions of app by making corrections in App Inventor, testing them by downloading the apk file. On my mobile, the apk has all changes made.

WHen I download aab file, and upload to playstore, I can download changed ICON, version numbers are reflected but the content is not having the changes made.

I created a new app entry in playstore, renamed the project, and uploaded new aab file, but still the content is old itself.

So I want to know if there is a way to test the aab file before uploading to playstore.

I thought so far that it might be due to selection of wrong releases during production phase, but I see same issue even when new app is created with renamed project.

Can it happen that app inventor always downloads a older aab file?
