I agree, that is the least they could do. And this is not the first time a release breaks stuff - actually it seem quite common. It seems they either don't test (?!) - or have very poor test coverage. And still (!) there is no official fix for this issue. I am holding my "license renewal" until things improve. Getting very tired of basic stuff just not implemented - or not working.
My guess is, they are refactoring "tons of" fundamental stuff in their library. And that is probably a good thing. But that is no excuse to existing paying customers.
Also tired of the ridiculous long forum loading times, lots of advertising and buzz-dev-talk (on twitter, blogs, email etc.), missing/delayed support email and forum responses, deprecated documentation and infrequent offical releases/bug-fixes.
For me there is just gap between "what is being promised to the customer" (or the product price) and "what is being delivered". I hope they will manage to bridge this gap, as parts of their core product _is_ cool (e.g. for us, in theory, it's fantastic with a native multi-platform slick-looking charting library). But so far, not so good.
