Hello Admin and OP I just tried this now with an FBX 2014 Mixamo character and the animations that was exported to this character back when it became and i wanted to update the same as OP and the button is still greyed out. I can provide you with all files necessary, just provide me with a repository link or mailadress There is another issue with the new mixamo 2020 Exports that screws the skeleton up and i think it's something in the FBX 2019 version that makes it incompatible.. I can provide all those characters and animations you need or if i should make a new report Thanks

Did all character happen or only some character？Please save Mixamo chatarcter via 3DXChange,and provide the character and system information file to help us identify the problem.
