Problem Removing Team Members

Two owners of a Team are having an issue removing one member. 

Each of us have tried to remove the member numerous times over the past several weeks, both on the App and Web versions and we each get a notice that  "We ran into an issue. Please try again later."

We have both changed the other owner to member and back again, as per another recommendation on the forum, but that hasn't worked either. 

The member we are trying to remove is not a channel owner in the Team either. 

We are able to remove other Team members, just not this one. 

Any suggestions?
