Cannot log out of Bentley Account

I have two accounts with Bentley Communities, and have had them for some time.

I have the business account, which is connected to my employer for IMS authentical for licensing, support and such. This account is not perpetual, in that if I were to change employment, I would be assigned a different account. This will hereafter be referred to as "BM"

I also have a personal Communities account that I have had for about as long as there have been Communities. I have the personal account so that I can maintain a consistent online presence, and so my participation is not limited to my time at any certain employer. Hereafter referred to as "MB"

In the past, it seems that I have been able to log into certain portions of the Bentley site with one account, while logging into another area with the other account. For example, I could stay logged into Communities as MB and I could open another browser tab to the Service Request Manager and log in as BM. This never seemed to cause any issues unless I accidentally chose the wrong account for a certain area (easily fixed).

Today, I attempted to go the the old Service Manager so that I could try to collect whatever is left of my old service requests since they will no loner be available through the new "service portal". I was unable to log into that site separately since I was logged into my communities account. Fine. I logged MB out so that I could turn around and log BM in. That was only so successful (but that's a separate issue). With my business completed at the moment, I attempted to log out of BM and I got the following error message:

Forbidden
Policy Error
What on earth is this? Why am I "forbidden" to log out of my BM account?

 I do not want my online persona chained to my employer. I want to be able to switch back and forth as needed.
What did you change, why did you change it, and when are you going to fix it?
