We offer a summer session where parents of candidates log in with their personal email to sign the contract, etc. We have not been issuing invitations when their BBID is set up, just an email with instructions to login to our instance and follow the prompts. This works for about 90% of our parents. Several parents have encountered problems logging into our system when they are already using the same email at another school even when they delete cookies, open an incognito window, try another device, etc. The only way it seemed to work for them was when I issued an invitation to connect to our system out of Core.
I am having a hard time pinning BB Support down on whether issuing an invitation is required when using the same email with another system. Does anyone have any experience with this?
