No reply on the feedback submitted. Is this expected to not hear back on the feedback submitted for couple of months?

This is the first time I have submitted feedback so I am guessing the feedback number is what you are referring as bug number. In my case its FB9000387.

Thanks! I have submitted a feedback. Will update the thread once I get reply.

Thanks for the reply. The reason I used the GetValue is to be able to see if it was getting called by adding a print statement. I tried changing the code to directly use the CustomString as you suggested as well, but it did not work. Have you tried the code on Playgrounds on IPad? I am suspecting that it might be an issue only on iPad. Also how can we escalate to this to Apple Support?
