For people who work during the official chat support hours, there's no way to reach support. There should be an email option or other way to leave an offline message for issues the chat bot cannot solve.
It used to be that if you chatted after hours, it started a ticket and they would chat/email back during their business hours. And then the bot took over and now, after hours all you can get is AI suggestions of dubious quality.
The best thing to do is post your question. One of the coaches will respond the next day. Also, sometimes a fellow user will be able to help, and then you might get an answer sooner.
