Hi Windsock,
To the best of my knowledge that’s always been the case with dLive Director. What you’re saying about the minor releases being compatible is true for all our iOS apps, but not for Director. Director is effectively a virtual dLive running exactly the same code, so you’ll need matching firmware, like you need matching firmware on the MixRack and Surface.
I can see where this might catch people out in the field. The only solution I can think of is to make older versions of Director available on the website, so you can access the right version when you need it.
