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?

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

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.

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