Is anyone having editor issues?

Running the latest version, no plugins, default theme with minor css changes and ad code added in. I've also ran a pure default theme myself and still have the same problem.

I have also tried removing theme resources from the CDN.

Basically on iOS both iPad and iPhone the editor is retaining posts after they have been made with the content has been restored message, it's random but fairly frequent.

Other times pressing submit does nothing, when this happens you also can't upload an image.

I did contact support but they can't do much with it being random, I need to be able to replicate it which is understandable. Is anyone else having the same issues?
