I have created a private app in the app store via Home.mendix.com. After publishing the app, I can not download the app in my project. Is there a possibility to import it in Mendix 4?
The private appstore in only available in Mendix 5. You can download a widget in Mendix 5 and copy it to Mendix 4. This is not possible for modules because the file format differs between 4 and 5. Use dropbox or mail.
