I know a lot of you are having an issue with mp not starting after it updates. That's because we are restoring some of the data on your mp and it will take some time to migrate the data to your Mass Planner.
Please wait for it to start and don't close Mass Planner or any running task in the background.
User reported that it took up to 20 mins before it started. This depends on how many IG accounts you have.
This is a one time thing and this will not happen again after it's done.
