Preston, You are guided so useful info; I also prefer to write or view someone answer upwork forum to get solutions. But when its gonna unevitable then go to upwork support and create support ticket.
In general, you can to to this page, click Get Help button at the bottom of the page, share some information about your account issue and you'll be able to access your options to contact support. That said, just as Preston mentioned, you can share your question or information about your issue here and we'll be happy to help you or connect you with the team that can.
No need to contact the support team. You can easily write here about what issue you are facing the contributors & mods will hopefully help you out 24/7...!!!
