Tangerine Bank changed their login from PIN to password recently. Since then I haven't been able to reconnect my banking - Quickbook are not being helpful. anyone else?

Since switching from a 4 digit PIN to an alphanumerical passwrod I can no longer connect my Quickbooks transactions to my Tangerine Bank as Quickbooks is still prompting me for a PIN and wont accept my password. I spoke with Quickbooks last week and they said its not their problem it's on Tangerine.... I spoke with Tangerine and they said it's on Quickbooks to fix.... I went back to Quickbooks and they said they'll look into it - surely I can't be the only person finding this problem? Frustrated that the only way i cna log a complaint is to use the chat/phone call options and have to explain it all again for a third time. Has anyone else found this?
