You continue to be DEFIANT as you have been for the last decade. The delay is NOT SHORT, the bright flash, which can repeat so many times, is DISRUPTIVE and DISTRACTING on eyesight especially in dark mode. "Sorry to bring you inconvenience and imperfect experience" - that's also why people don't pay for your "high end" products.
CHANGE THE DESIGN - it's not by design - it can be CHANGED. I can even change it for you - hire me. There is so much mismatch/inconsistency between your office suite products - it's ABSURD. I can interactively zoom acceptably in Word and in Powerpoint, but Outlook has to be different and provide a poor user experience. The change would take 1-3 weeks to make.
I never give feedback using any of your software and block all telemetry.
Pay attention NOW!
