After the recent Discourse update on our site, i see a bit of an overlap between Solution “marker” and over elements when using on mobile (Latest Chrome, Android 10):
I don’t see this here. And here it uses different checkmark style. I don’t remember exactly, as i’m not the one who set our Discourse up, but i think some solution add-in was used to add such functionality. Maybe it is not needed anymore and there is a built-in feature or maybe here different add-in is used?
