In Sharepoint 2016, I've created a new link on our top menu. When I click Edit Links, and then try to drag it into a dropdown in the same menu, and then Save, I get the following error.
"There was a problem. Some of your changes may have been saved. The operation is not valid on the pinned term: 'Tools & Resources'"
"Tools & Resources" is the name of the dropdown I wanted to add the new link to.
Any advice would be appreciated, thank you!
