User not receiving Bitbucket invitation email

[Suzanne]

Use is not receiving the Bitbucket invitation. We canceled and resent the invite but they are still not receiving it.

I had them check their Atlassian email preferences and they did not have 'Product Invitations' checked. They checked 'Product Invitations' and I cancelled the invitation and resent it. They are still not receiving the invite. The user mentioned that when they checked 'Product Invitations', a message displayed indicating it can take up to 5 days for the changes to take effect. Do we need to wait several days for the invite to send?
