Yeah, same here. I renewed my Continuum license in April 2018. Not happy with the fact that I have not been able to use Continuum for many months now. With hindsight I should perhaps have delayed upgrading to Mojave (and not being able to upgrade FCPX and other applications), but at some point you have to take the plunge.
It looks like FCPX support is very low on BorisFX’s priority list. Also perhaps indicated by the lack of proper FCPX documentation (e.g. Reframer) and supporting only a subset of features of the other platforms (although at a lower price). Same thing happened with the previous release. And it’s always Continuum that’s giving me trouble. None of the other plugins I own have these problems, or their respective companies fix them promptly (or even before the new OS is rolled out).
I’m not holding my breath for a new release, and my license to upgrade expires in April. I’m not sure if I’m going to renew my license. Maybe just write it off and look elsewhere.
Sorry for the rant…
