Yes, that looks like an error on our end. I'll ask our developers to look into it for an upcoming release. Thanks for letting us know!
Thanks for the feedback. Whilst I appreciate that any bugfixes and their deployment are not always something that you'd be able to give ETAs on, are we talking a matter or days or a few weeks? The only reason I ask is that I'm working on an application that will be relying on this so that folks can easily RSVP to events on the go :)Nik
