Extension not replacing anything

[guidezpl]

I've activated the extension, and even tried it in an incognito window with no other extensions enabled, and no replacement is happening.

0 titles and 0 thumbnails have been replaced since you installed this extension

Any troubleshooting steps?

I've had a similar problem, and i think it may be caused by a UI experiment dearrow works on pages where the upload button on the masthead is just the icon, but doesn't when it's the button marked "create"

[koiz-koiz]

okay upon further inspection, the experiment is having the masthead and chipbar be translucent, like ambient mode. using inspect element the experiment consists of 2 parts, backdrop-filter-experiment and button-shape-next
