Hey Maureen!

I’m sorry to hear this is happening. What plan are you currently on? 

If you were on the free trial or a paid plan before but are on the free plan, now, you will not be able to access paid features (like adding/removing users from your organization, events for other users, workflows, advanced integrations and so on). 

If you are seeing a prompt to upgrade, I am betting you are now on our free plan, and will need to upgrade to do this and use other paid features. I hope this helps!
