I'm sorry you're having issues with your maps. Can you send a screen shot of your tagging, this way we can definitely rule it out as a problem? You're certain that you added the maps to a group that has the "M4CC" tagging on it?
Also, when you added your tags, did you have the extension opened? If you did, then that could also be a reason. Sign out of the extension and then sign back in. If you added the tags as the extension was opened, the changes will not appear automatically on the extension.
Hi Nancy - I am attaching photos of my group, one of the maps and the CC dialog window showing my folders. Thank you for your help. I have tried singing out and back in of the extension and that did not solve it.
Ahhh! I was just clicking on that button (which automatically opens the add layers dialog). I just tried right clicking on it, which allowed me to see the dropdown (I didn't know existed) and choose 'Add Web Maps'. I now see my maps!!
