Trying to accept an Eagr invitation and seeing "User already exists. Use another email"? It happens when an account already exists with that address.
The most common cause
You created an account directly instead of going through the invitation email link, so it's not linked to your organization. Since the address is already taken by that account, the invitation can't apply to it.
What to do
Email us at support@eagr.ai with the address in question: we'll attach your account to your organization so you get the right access and your license.
Tip
The golden rule: always activate your account from your admin's invitation email link, never by creating a separate account. On the admin side, invites are sent from Assigning and managing licenses.
