Live Activities not working on Macbook with Tahoe installed

I am not able to get Live Activities from my iPhone to mirror to my MacBook. Both devices have the newest OS installed from yesterday's release (iOS 26 / MacOS Tahoe).

• Notifications are enabled on each device
• Handoff is enabled on each device
• iPhone Mirroring is enabled on the phone
• Signed into same Apple ID
• Wifi/Bluetooth ON on both devices
• Live Activities enabled for the app(s) in question (Flighty, Apple Sports are the ones I've tried so far)
• "Allow Live Activities from iPhone" toggled ON in Macbook Notification settings.

What else am I missing?!
