It has been about 3 months since I accessed my App in Mendix Studio (version 7.15.1). I just tried to open the App for Edit and I got a “Failed To Start Mendix Studio” message saying – The Syncing method for this App is not supported anymore. A brand new, much smoother sync feature is available now for apps with version 7.23.3 or higher. Can anyone explain what I need to do to access my app? Thanks
What I would try doing is opening your app in Mendix Studio Pro in the latest version of 7 (i think 7.23.7) and then selecting to update it to that version. After that you should be able to open your app in Mendix Studio. Then if you want you can eventually update your app to Mendix 8. But just to get it working that should do the trick.
