Harshil Sharma a718840c8f Addressed review comments on channel write access
Hid pinning and the acknowledge button while a write access policy denies
the channel, as the server refuses both, and moved the read-only notice to
app/components since two screens share it.

Mattermost Mobile v2

  • Minimum Server versions: Current ESR version (11.7.0+)
  • Supported iOS versions: 18.0+
  • Supported Android versions: 11.0+

Mattermost is an open source Slack-alternative used by thousands of companies around the world in 21 languages. Learn more at https://mattermost.com.

You can download our apps from the App Store or Google Play Store, or build them yourself.

We plan on releasing monthly updates with new features - check the changelog for what features are currently supported!

Important: If you self-compile the Mattermost Mobile apps you also need to deploy your own Mattermost Push Notification Service.

Frequently Asked Questions

How is data handled on mobile devices after a user account is deactivated?

App data is wiped from the device when a user logs out of the app. If the user is logged in when the account is deactivated, then within one minute the system logs the user out, and as a result all app data is wiped from the device.

I need the code for the v1 version

You can still access it! We have moved the code from master to the v1 branch. Be aware that we will not be providing any more v1 versions or updates in the public stores.

Troubleshooting

I keep getting a message "Cannot connect to the server. Please check your server URL and internet connection."

This sometimes appears when there is an issue with the SSL certificate configuration.

To check that your SSL certificate is set up correctly, test the SSL certificate by visiting a site such as https://www.ssllabs.com/ssltest/index.html. If there’s an error about the missing chain or certificate path, there is likely an intermediate certificate missing that needs to be included.

Please note that the apps cannot connect to servers with self-signed certificates, consider using Let's Encrypt instead.

I see a “Connecting…” bar that does not go away

If your app is working properly, you should see a grey “Connecting…” bar that clears or says “Connected” after the app reconnects.

If you are seeing this message all the time, and your internet connection seems fine:

Ask your server administrator if the server uses NGINX or another webserver as a reverse proxy. If so, they should check that it is configured correctly for supporting the websocket connection for APIv4 endpoints.
