Yes that is pretty much what I have been doing – but you need to wait for the response to time out – 30 seconds on my server – so this is a time consuming and inefficient workflow. On the bright side, I suppose it gives you the chance to contemplate where the screw up fairy just waved her wand.
It would be real nice for someone to come up with something more novel.
@okadots Yes I am having the same issue – I have tried with BETA 2 checking Elliot’s fix above has been implemented, and the problem occurs here too – can register blocks and setup Custom Fields for them – but they are not available in the Gutenburg Editor.
