I have the CloudDataSetDemo VCL demo working. I also have the CloudDataSetDemo Google Datastore working, but I cannot get the web authentication screen to come up for CloudKit on FMX for Windows.
Seattle and as stated it does show the browser for the VCL version. It also shows the browser for FMX when using the "Google DataStore" radio in the demo. It isn't getting the redirectURL from the json the same way as VCL. I've tried debugging it. I've even put the same ini for the tokens that are valid for the VCL version in my FMX project and it still doesn't work. I also have the same issue when using the iOS FMX demo on my phone. No browser to authenticate.
