Auto receptionist "route to user" not working

We had a power outage and had to make a temporary switch to a mobile number for our practice. The next day I went to switch back to a user, that option is not one of the drop-down options anymore.

Tried the chat bot with a few things like: auto receptionist "route to user" not working

- Bot response: Ensure you have selected a valid routing option such as Voicemail, User, or Call Queue If you have followed these steps and the 'Route to' option is still not available, please contact Zoom support for further assistance.

- My statement: The route to user option is not listed on the drop down. It used to be there.

- As a workaround, I used the direct line to the user (as would for an external contact). This internal user option needs to be available. What happened?
