Adblockers can block scripts that are also used for legitimate purposes.
You may find an adblocker that's compatible. You can see if your adblock will allow you to white list CoSo.
I use Brave, which has built-in, configurable adblocking & script blocking. Makes it very easy to adjust.
@Iskios I imagine it's because ad blockers don't just block ads. They can also block functionality or web pages from displaying properly 👍
