I have this issue and it really bites since I had merged my sites from another contact form plug in. The hope was that Jetpack with it's increasing functionality would reduce the workload associated with updates.
Alas that has not been the case and stuff like this makes me wonder if I have thrown in with the wrong team. Makes me want to add a follow up to my nice write-up of a then functional JetPack.
As it is I will start reverting my sites back to Contact Form 7 that works and then start looking for alternatives that play nice with the rest of the WordPress community.
Oh the irony of it all, JetPack not playing nice with the rest of the WordPress community!
In the meantime I am voting this "not working" until proven otherwise.
