Thanks for your prompt reply Paul. A very strange issue to run into! My first thought was a local issue but all router resets etc. didn’t resolve it. Additionally, when I create a test user for myself with the same role, apply 2FA then log in from my home computer I don’t get the issue. It’s only happening at our office. It really seems like it should be some sort of local issue, so I’m perplexed as to why disabling 2FA resolves it!
I’ll need to ask the guys to check console for the info, please bear with me.
