Thanks. The difference between your configuration and mine is that you added the condition “Owner is not current user” which for me is useless as assignation is done only if the owner is undefined… What do you mean by change execution is defined as “Owner = current user”.?
I’m in fact very surprised as after making the change you suggested back and reverting to my original config it now works as expected… Would mean that the original rule (created in 6.0 I think) was not properly registered and have been reset by the changes… I’m skeptical…
