Invite member Couldn't invite the following user:

I am trying to add members, and I get the same error Couldn’t invite the following user:
I have tried with someone who has a Cloudflare account 1 and someone who does not have a Cloudflare account 2
Thanks

I wonder if their e-mail domain somehow ended-up on some kind of a supression list :thinking:

May I also ask if your Cloudflare account is verified by your assigned e-mail address?

I wonder if the user is inactive or deleted his CF account?

P.S. Kindly, could you please edit your post content and remove the e-mail addresses due to the privacy concern and public posting here.
