One calendar doesn't sync withy iCloud calendar

Sorry for the inconvenience. Something has changed at Apple iCloud servers that makes our app currently not compatible with iCloud. Apple usually does not communicate over these changes.

We have build a fix a few days ago and are currently rolling it out to the stores (Android/iOS/Mac)

- ANDROID, fix is gradually being rolled out (may take up to a week). If you need a fix earlier, you can enter the beta program by going to this URL:
https://play.google.com/apps/testing/biz.codespark.xcalendarapp  
After accepting you will receive the beta version with the fix within hours through the Google Play Store.
The new version number should then be 2.0.0 or higher.

- APPLE iOS, the fix is currently being rolled out

- WINDOWS 10, the fix is build we the Microsoft Dev environment is broken so we are working on that to fix it ASAP so it can also go to the store.

Hi,

Something has changed at Apple, we are working on a fix ASAP.
