You are more than welcome to upgrade to M Premium at any time. Simply go to your account page in the app. Make sure you have the latest version of the app installed first.
If you’re currently on the Large plan and decide to try M Premium you will be moved over to M Premium when your current plan renews. You can see the renewal date in the app.
If you’re on the Lagom plan and decide to try M Premium right away, you will be moved over directly. You will be charged the monthly fee, and we will reimburse the fee you’ve already paid for Lagom the previous month.
