Workaround: Put a page right before your Thank You page that is not controlled by page logic. You could ask an additional follow up question here, or put in a Text/Instruction Element if needed.
Additionally, you could also move the page controlled by page logic up in your survey so it’s not the last page if this is more practical for your survey build.
We will work on fixing this up, so these should just be temporary workarounds!
This issue is all fixed up!
