Yeah, please don't suggest contacting support, there is ZERO value in doing that. I reached out again after receiving the message that it was resolved. The agent didn't understand that there was an existing issue on QuickBook's end, and he wanted me to go through basic troubleshooting again.

Support has a script they go through before they try to understand or help with the issue. Clear your cache, try a different browser, log out, etc. After burning 15-20 minutes of your time, they'll search to see if it might be a known issue on their end.
