Cannot login to this community forum for an ingress agent who registered with a non-gmail account
I post this thread for one of my friends, who registered for ingress 6 years ago with a non-gmail email address. Obviously he cannot login to this forum with a gmail/google account. However, even though he had associated his ingress prime account with a Facebook account, he still cannot login to this forum with the facebook certification.
He is an active agent, and has tons of opinions and ideas to share with everyone, so it will be a pity if he keeps being denied by this community forum. Fix this issue, please.
