Hi @mike.huebner

I can see that you have opened a support ticket on the matter. Unfortunately, I have not been able to finish the tests on my side regarding ACUL.

Since I will be OOO tomorrow, I would recommend keeping in touch with the designated support engineer on the matter and I will sync with them whenever necessary regarding troubleshooting the issue.

If you have any other questions or updates, please let me know!

Kind Regards,
Nik
