Hello. I’ve recently tried this app “Pace” and I no longer want it to be activated, so I tried to uninstall it. Uninstall process finished gracefully, but my site is still showing Pace loading widgets - even if it is no longer showing “Pace” as an installed app on Cloudflare Apps tab.

Do you know if I’m missing some step to get this widget cleared from my site? Thanks!
