How To Mute Match Invites
You can control match invites in two different ways, depending on your preference.
Option 1: Turn Off Match Invites in Settings
This will stop all match invites from being sent to you.
Step 1: Tap your profile picture
Step 2: Tap the Settings button in the top right

Step 3: Tap Notifications and Invites
Step 4: Tap Notifications and Invites again

Step 5: Toggle off Match Invites

Option 2: Mute Invites from a Specific Organizer
This will stop all invites from a specific organizer.
Step 1: Tap the notification bell in the top right
Step 2: Find an invite from the organizer

Step 3: Tap Mute Invites

Note: Muting an organizer will stop all invites from them, not just matches. This includes tournaments and other events, so use this setting carefully.
This gives you full control over the invites you receive, whether you want to stop them entirely or just from certain organizers.
