All the effect checkboxes have now been set to ON by default, and are sticky (meaning that if you disable preview, on next launch of Illustrator preview will remain disabled). This functionality now is available in our latest release build – 24.1.1 for Win and 24.1 for Mac which is available worldwide now.
We are working on making all remaining preview check-boxes sticky. Will update this thread when done!
