New Device Missing in IDE

I have been running the new smartthings app successfully for about a year plus webcore for all my automations. Until just this week, when I add a new device in the ST app, it shows up in the IDE, and then I can make it available to Webcore. However, I recently added a new device in the ST app, and it hasn’t appeared in the IDE, and thus is not available for webcore neither. Anyone have any ideas on why the IDE is not showing the new device please?
