Hi Ann, thanks for your reply. For now I will simply use the manual export. I've went through the motions of clearing preferences, re-installing and cleaning due to a new laptop and another problem, so I'll avoid that if possible 🙂
Thank you @Averdahl, I got the Quick Export button back with your suggestion. Although I had to use "All Panels" instead of "Revert to Saved Layout". Apparently I created a workspace and saved it without the QE button. Thanks again!
