By default, keeping Ampll up-to-date requires no manual intervention. Ampll checks for updates periodically, and it downloads and prepares those updates in the background.
You can prompt Ampll to check for updates immediately from the Preferences window available from the "..." menu of the Mini Panel.
Then, from the Account Info tab, click Check for Updates.
To apply updates, Ampll needs to restart. By default, Ampll restarts automatically when the Dashboard is closed and it does not detect you are in an ongoing video call.
You can choose to toggle Auto restart on updates to Off. When auto restart is disabled, Ampll typically presents a notification to restart. Clicking the notification typically restarts Ampll to install the update.
If you ignore or do not receive the notification, you must quit and restart Ampll manually.
