Hi @daudau,
Thank you for the additional details. I think at this point it would be best to go ahead and get a ticket submitted. It might be helpful for us to get a temporary admin account, which we can do securely via a ticket.
Please do so at the link below and include a link to this forum thread. Once we have this, we will be able to investigate further and do some additional troubleshooting together.
