Hi. Have you updated to the last version? I have the 26.0.1 version and I have a smaller monochromatic button.
I have the newest (26.0.1) version as well. No matter what my UI brightness is, that button is bold and blue.
Maybe if you use the button once, it become gray.
I tried that, clicking the blue button and Illustrator crashed after clicking cancel.
The second attempt worked, I could click cancel an the blue button has disappeared.
You guys are great. Such a simple thing. I clicked on the button, then canceled, and it went away. That didn't work when I had 26.0. Does now. Thank you!
Good to hear that helped (I found it distracting too).
Haha I'm not alone! I agree that this button is distracting.
