Your welcome
Hmm… Ben ( @ben1 ) has replied in this conversation.
Renaming the release doesn’t work in this case at it’s taking the APK file version that is listed in the file, not just the release or file name.
I ran into this issue yesterday as well because I had already used the APK in a previous release. So you can start a new build in Adalo, or be sure that you are selecting the latest build and that has not already been used in a release on Google Play.
I have to say, it took some help docs and stack overflow threads to fully understand how the release tracks worked on the Play Store Console. It is mostly intuitive but has some small quirks that are confusing.
Thank you
