What if I own multiple venues? Your venue access in Prismm will carry over to your CED account. Your venues will be organized under different team accounts.

If you work across multiple venues, your venues are organized under different team accounts in CED. This means that the venue, event, and diagrams you’re looking for will appear only if you’re viewing the correct team account. To switch between accounts, click on your account name, then click “Switch Team Accounts”. Select a different account to see the venue details, events, and diagrams associated with it.
