There was an update released yesterday so I’m thinking it’s just a temporary glitch.
Also worth mentioning, there were some subtle changes to the MDX app with this latest update. Not the least of which was the removal of the “Change Party” function for FPs. If anyone has an upcoming trip and planned to possibly using this function if say, Grandparents decide to hang back at the resort, or one parent has to take the toddler back to the room while the rest of the family stays in the park, it might be best to postpone downloading this latest update. You’d also want to disable “automatic updates” on your device.
