I would suggest to open the desktop modeller on your PC without the Mendix Portal and then click on open project from SVN and select the name of your project. It should be the MAIN branch if you haven’t created a new one. Then it should download your app.
did you take the steps mentioned in the following article?
Thank you all.
Indeed, I have enabled the collaboration. Still it only opens a blank app in Desktop modeler.
But when I view the App through Desktop Modeler, I can see the original App. Confusing for me.
Dustin, which version of the Desktop Modeler / Studio Pro are you using?
Please have a look at the following documentation for synchronisation between Studio and Studio Pro (Desktop Modeler).
