I am beyond disappointed with Canon that there has still been no fix to make Print Studio Pro work with the new Apple update from one month ago. Since updating to Big Sur 11.6 my printing ability with my Pixma Pro 100 using DPP4 and Print Studio Pro plugin has been completely broken. My computer locks up and I have to force quit to get out of the program. DOES CANON plan to do anything about this??? I'm not so good at being patient beyond a reasonable amount of time I want my equipent to work again.
