From Android 14 it is no longer possible to install any application that targets below API level 23 - Android 6.0. Attempting to do so will trigger a security exception. Applications already installed will remain untouched, however new installs on any device that hasn't previously had the application will fail.
Be sure to update your applications to target a recent API level (or at least 6.0) before deploying any Android 14 devices into your estate. This will become a rolling policy, incrementing an API level with every future release.
