Can no longer reboot Smartthings Wi-fi

I can no longer “reboot device” (Smartthings Wi-Fi) in the Smartthings app. Anyone else experiencing this as well ?

Is reboot device the same as reboot hub?

Are you able to reboot hub in the Advanced Web App?

In the app, Select the Hub > Network Status > “Select Hub”
Under Hub Details, select the 3 dots. Reboot Device and Factory reset.

The Hub will not reboot. All I get is: Can’t connect to your Hub. Try Again.
It appears to be an App issue. I can reboot under the Advanced Web App.

The Advanced Web App only allows you to reboot the Main Hub. Not Sub Hubs. I need to reboot the Sub Hubs
