I guess you have added the button on the simple list? That won’t work because you can’t access current item data when you add a new component on a simple list. So what you need to do is remove the simple list and add a custom list and then add the button into that custom list and you will able update with current question data!
It is sporadic. It is working as expected now, however a few days ago if I answered the same question with the same user multiple times, or logged in as a different user, it would not link the Question. I’m not sure the reason for it not working as I don’t see a pattern I can hone in on. For now I"ll say it’s fixed.
