Editors are since the last update not able to change there own post

Hello,
I have been using wp user frontend for almost 2 years now. It always worked fine. But since the last update is doesn’t work good any more.
I tried to roll back to an older version. This succeeded but the problem was still there. I tried several versions but nothing would helped the problem.

See the post of tholub (@tholub) which described the problem.
I know that this problem is send to the githubb.

My question…
Does the pro version has the same problems? I really want this problem to be solved and im willing to pay for it
