Hello,   I am trying to copy summary page items from one app to the other but i am receiving following error message. Does anyone know how to update the app version in web studio? Currently studio pro is not working so i am using only mendix web studio for now.

As far as I know the only way to upgrade to a new version of Mendix Studio is to open the project in the new version of Mendix Studio Pro and do the conversion there and commit the project. Then you can open it again in Studio and it will be on the new version.
