Deploying to mobile isn't as transparent as web: every Connect update nags the user to install it.
Continuous delivery like that doesn't offer us the possibility to let builds accumulate until a release, saving user's data and giving us time to rollback when problems arise.
Currently, with our new in-house MDM solution, we don't have a way to control which builds get deployed to Android devices, all builds are consumed by Connect mobile clients as soon as they are uploaded to Nitro and the client downloads them.
