I was able to successfully login to the Monzo Developer Portal yesterday but after logging out, I’m no longer able to login.
When I attempt to, I receive the “Log in to Monzo” email but the link in the email takes me to the following (redacted) error:
<Error>
<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>
<Key>login</Key>
<RequestId>6QYRQH5[REDACTED]</RequestId>
<HostId>x4XPOI68Z[REDACTED]ZSd5I1Kr7ZwrENQwX+zIWi/nEt+94=</HostId>
</Error>
I’ve tried multiple browsers and devices, including guest and incognito profiles. Always clicking the login link from the same browser that initiated the login.
