UK Phone Number Required for Codex BROKEN

When downloading CODEX, it asks for a phone number to login.

For UK customers, Codex adds a ZERO after the +44 which does NOT work. So authentication is impossible.

Example: I enter +44 7501 234567 but the system turns it to +44 0 7501 234567 which does NOT work. I never receive the WhatsApp message and I cannot sign in, using this method.
