I recently had an issue submitting a new app to the playstore because it was insisting on SDK 28 and by default Meteor was building with 27.
I followed the steps here to use a hacked project.properties in cordova-build-override/platforms/android with target=android-29, then I successfully built and uploaded it:

I used 29 instead of 28 not realising that it wasn’t officially supported by Meteor’s Cordova, and thought I might as well get the latest.
It’s currently in beta testing but so far its working ok…
