FAQ
Q: Is there a specific version of the Mattermost server required to use the mobile application?
A: Yes, it is strictly required that your Mattermost server is running version 10.11.0 or higher. Using an older version of the server will lead to connectivity issues, data synchronization errors, and an unstable experience, so please coordinate with your administrator to ensure you are updated.
Q: What happens if I try to connect the mobile app to an outdated server?
A: Connecting to an incompatible server version can result in critical errors and unpredictable behavior across the application.
