The AppCloudServices module has been deprecated, please check the documentation: https://appstore.home.mendix.com/link/app/934/Mendix/AppCloudServices
It seems there is a beta of the new OpenID integration. referenced in the AppCloudServices documentation. You could try downloading that.
You could also just give Mendix a call, maybe there is already a new version available.
Hi Tim,
In my opinion you should file a support ticket: The AppCloudServices module is a Mendix addition to the AppStore, and has platform support, so it should be fully supported in the latest version Studio (Pro).
