After a number of though the support channel and the management feedback channel, they have given me a key for one year of pro use, though I really wanted a refund.
That fact that the limitations are mentioned in the manual is irrelevant, the function of the edition comparison page at point of purchase is to point these differences out, it did not. This amounts to false and misleading advertising at best. Any one experienced with parallels, is unlikely to read the manual every upgrade.
I actually got mad when support stated that it was a mistake that the standard version had this extra functionality and that update 12.1.0 "fixed" this issue. I'll not deal with any corporation shows shows such disregard for customers that it expects them to pay for corporate mistakes.
