Hello,
Forgive me if I missed a dedicated forum/thread where we can give feedback on the new client experience that has been released with October's update.
Some users who switched to use the new experience reported that properties that have 'Set value' (mode 'Dynamic') don't show anything when a new form is initiated (this was also an issue that was persistent in the 'new' Web interface for quite a while although it was fixed at some point).
