Animation Tick Rate Reduced in 4.20

In 4.20 the Animation Tick Rate is reduced when the server palyer sees a client character.
Only the chracter skeletalmesh component seams to be affected. Its easy to reproduce.
Just create a new 3rd person template and set number of players to 2. The server player will see the client character animations are not updating smooth.
is there any work around for this?

I found a bug report in the issue tracker: UE-62225
