The portal auth error is a red herring. There’s a check on entitlement for Advisors downloads and if you’re not authenticated with a portal account you just get the advisors bundle for anonymous users.
I think this is a bug but can’t for the life of me piece together what would cause it other than some missed component that accidentally was left in for the SQLite to Postgres migration. I’ve escalated to the dev team to look at it. If you create a ticket you’ll get automatic updates when we make updates but if not one of the devs will create one and I’ll try to remember to update this thread so you can manually follow.
