The latest iOS version beta has certificates support. Though it’s still work in progress.
Click Contact Us to let us know if you are interested and we’ll provide you with the access to beta.
In the next months we are going to add the certificates support on all platforms. No exact ETA at the moment, we are just working on it now.
