I paid for Canvas Draw 6, but I've never been able to use it because of terrible performance. I've been patient because I assumed they would fix the problem. Meanwhile, I'm still using version 5. I certainly won't subscribe to software that is unusable, so I'll just stick with 5.
Are they going to refund the money I spent last year on an unusable upgrade?
As far as I know, Canvas is not subscription only, they have the subscription service on sale. If I'm not mistaken, they still sell it outright and have a software assurance program to buy a years worth of updates. It is disappointing that v6 is so problematic, but as important as Canvas is for me, I'll live through the trials and tribulations.
