"ADD A BLOCKLIST" feature is not working

Hello, I am trying to add a new blocklist URL in the "Privacy" tab, but the feature is not working. When I click "ADD A BLOCKLIST" and paste a URL into the input box, the "ADD" button does not appear. We have thoroughly troubleshooted the issue: - I am using the correct procedure. - The problem occurs in different web browsers (Chrome, Firefox). - The problem still occurs on a completely different internet network (mobile hotspot). This indicates the problem is specific to my NextDNS account. Please investigate and fix this issue. My Profile ID is: [73833c]
