Hey Matt J. I actually got a fix on this yesterday I also have noted that the js that comes with the countdown timer needs fixing as the code for it to stop at 0:0:0 is not in the right order so the timer has continued into the negative.
The timer also has an issue if using as a CMS timer, which causes issues because of Webflow lacking proper time formatting, but I got a fix on that as well, I will do a video and I hope that can result in the timer to be updated in the components library.
