Unable to add members to Blackmagic Cloud Project Library

I'm using DaVinci Resolve Studio 18.6.4 Build 6.

I have a Project Library in the Blackmagic Cloud, with myself as the sole member. When I click "Share" in the project manager in DaVinci Resolve, a web browser window opens with the URL `project-server.cloud.blackmagicdesign.com`. There I see a view similar to the project manager in the app, and when I try to share the project with any collaborator, I receive a message that says "Email <X> has not been registered", even though I've confirmed that the users have registered a Blackmagic Cloud account and verified their email address.

Notably, my experience with DaVinci Resolve Studio 18.6.4 does not match the "Getting Started With Blackmagic Cloud" tutorial on YouTube. In the YouTube video, clicking "Share" in the app opens a window in the app, rather than opening a new web page. Is that to be expected?

I'm having the same issue, did you ever resolve this?

NEW - Once the project library opens in the web page, click the Details (i in a circle) on the right, choose the Sharing tab, then pic Share Project Library from the bottom. Prompt for email shows there.

Having the same issue with the message about the E-Mail not being registered. Could you resolve this?

SOLUTION:
The user you want to add needs to:
- register a Blackmagic Cloud account
- Verify their email
- LOG IN AT LEAST ONCE on the Cloud website

The last point was the one that did it for me!

Thank you.
I think you saved me for severe frustration.
Your instructions worked for me as well. I'm glad I read them before emails went out to a team.
