Hi Andy,
What I use is our internal test system, so the support package is the latest one.
Because this is a new function and we cannot be sure whether all of the business scenarios are fully tested , it is hard to say whether it is a new bug or not.
If you believe it is a bug but cannot find a correction, you may consider to create an incident. Then I can check and confirm it in your system directly.
After it is solved, we can share it here.
Best Regards,
Sheldon.
