We are a company that has just starting to Using MDM tool. For IOS apple devices we force users to use latest version for security. But what about for Android, what is the best practise. We have about 2500 android devices from Android 4 to Android 9. The easy thing would be just to require latest version, but will cause a lot of users with older devices not to connect to company email etc. So anyone with recommandation what could be the initial base line?
