Renaming of pins does not work any more

Since last week we cannot change pin names in existing project and also not in new projects.
We use mainly customs symbols like Part Body and apply pins to this symbols also via Custom symbols.
Any idea what the problem is ?

@georg.nendel - Thank you for pointing this out. The Scheme-it team has made a change to fix this issue. Can you please verify?

Also, have you tried our Symbol Editor V2.0 for building custom symbols? Please let us know if you have any feedback.
