Mobile app release process

The Mattermost Mobile Apps team works on a monthly release process, with a new version submitted to the iOS App Store and Google Play Store on the 16th of each month.
Please refer to the Mobile Release Playbook for a most up-to-date checklist.
Note: iOS App Store approval may take a few days after the 16th.
