If you are unable to find a Meal Plan, that can be due to the different settings required per Meal Plan.
You can find all the details about the settings required per the Meal Plans here.
Please follow the instructions. Should you still not be able to see a specific meal plan though you fulfill all prerequisites, please contact support with your current in app settings, the current goal you have set and the plan you are trying to find.
