I have a phone project, as well as a watch (wearOS) project. 90% of the code is shared between the two projects, and I would like to package and distribute them in the same store listing. Note: All shared code exists in a common library module.
I have tried adding the watch project as a module to my existing phone project, but when generating an app bundle for release it outputs two bundles, one for each project. In the past releasing with multiple APKs targeting different devices seems to have been possible but with multiple app bundles I receive this error in the play console:
You can't rollout this release because it doesn't allow any existing users to upgrade to the newly added app bundles.
I'm looking for solutions to be able to release both projects in the same store listing, documentation on this topic seems sparse or I'm doing something very wrong.
