We getting an errors by importing single Microflows from 7.20.1 apps to 7.20.1 apps. By the import of modules between the same apps, we're getting no errors.
Does anyone else has this problem?
I ran into the same problem using 7.20.1
Workaround (when im-/exporting a MF from module 'App'):
Importing this modified .MPK file should work again.
I also had this problem. The only workaround I found, was importing the whole module, copy the microflow to you rmodule and delete the imported module again. A lot of overhead.
