ICloudKit and manifest errrors

Hello, iCloudKit is not working well to sync my inbox database across 2 macs, one iphone and one ipad. I get a constant stream of manifest errors. Everything is on the latest version of DT3.

Reply to self… arcane setting in DT3 on IOS… left swipe on the inbox in the icloudkit sync locations reveals the location of paradise… Empty Database in red. Errors are gone!
