great reply! thank you for including links to the files. googling such things is a nightmare. To make my .aab get accepted to android dev console, i had to install java to the android studio directory to make use of keytool for the keystore file. Is that still the case? do you have experience with this where you can tell me if i should just install java 11 as i would normally, and then change system variables i.e. java_home?
