Sign in around Organisational Account

Anonymous Ok. So here is what I found. There is no issue with either incognito or a different profile provided you are using a different domain. The pain is when you have multiple accounts using the same domain.

The only way around this, that is currently broken for me due to network configurations, was to set up a virtual machine that I could spin up on my desktop to log into, then connect using the other set of credentials. I think this VM was stood up outside the domain somehow (I forget) - which is why this worked. The only other bit I've found was this post about trying to bypass the behavior, but I don't want to muck around with this on my machine atm.
