Thanks for checking back in with us about this. Unfortunately, we have not been able to determine what may be causing this behavior at this point, but I will raise this issue with our technical team once again and see if I can get any updates.
I am going to create support case about this issue on your behalf in a moment and will keep you posted on any additional information which becomes available through that case. You should receive an email with the details of the case as soon as it has been created.
We apologize for the continued difficulties.
