Error Copy from FamilySearch Tree into Family Group I created

P7181

I created a Family Group. When attempting to "Copy from FamilySearch Tree" into that Family Group, I receive error message … "There was an error while trying to copy persons into this private tree. Please try again later." I "Select People to Copy" by clicking the checkbox under applicable individual names and then, clicking "Copy to Group". The same error message displays whether I select a single person or multiple people to add to the group. The same error message also displays when attempting same action using either Google Chrome or Firefox. I have deleted browser history and cache. I have logged out of FamilySearch and restarted computer. Same result is received. Any suggestions? Thank you.
