Hi there! I understand you're unable to access the admin dashboard or add events on Stack Team App. Let's work through this together to get it sorted out.

First, just to clarify:
- Are you still able to log into your account, or is access completely denied?
- Have you recently changed any settings, your email, password, or your role as an admin?
- Are you trying to access the dashboard via the iPhone app or through the website?

Meanwhile, here are some common checks to start with:

1. Confirm that your admin rights are still active on your Team App account. Sometimes admins can be accidentally removed or demoted from access groups.
2. Double-check that you're logged into the correct access group for your team in the Stack Team App.
3. If you're on the iPhone app, try logging out and back in, or uninstall and reinstall the app to refresh permissions.
4. Access the admin dashboard from the web at www.teamapp.com using Safari on your iPhone to see if the issue persists there.

If none of those work, we can explore deeper options like verifying your admin status via another admin or the root account, or checking for any account-wide restrictions.

Let me know what you find from the above, and also if you get any error messages or specific behaviors when trying to access the dashboard or add events. That will help me guide you more precisely.

Also, do you have the latest version of the app installed? Sometimes an update can resolve such access issues.

Looking forward to your reply!
