If you're a web developer or expert user, the summary is we'd like you to send us a network recording HAR and browser console logs.

Please try disabling any ad blocker or browser security extensions first and then retry before you go through these steps. If that fixes your problem, we'd still appreciate you letting us know your browser version, ad blocker or browser extension, and the website URL.
