If you had 6 users, you were not converted to a free account (obviously).
I had an account that became unneeded today, so I removed it... and then I contacted support about getting the free plan.
Their message about contacting support to get switched over is basically a lie because they tell you to delete your account and sign up new.
Sure, I'm paying for it now and get value from it, but every dollar matters at this point and if they are gonna help me save $10/month then I'd be happy! But instead I feel jaded.
