Thank you for the update, and I appreciate your efforts.

I will find some time this week to test and share my feedback. In the 
meantime, would it be possible for you to test using two instances (Test 
Case 2)? I did not encounter many issues when testing with a single 
instance.

I believe that testing with two instances increases the likelihood of 
reproducing the issue in your setup as well.
