Beta, eh ?? Think yourself lucky.
As I incessantly bang on about, because it's shooting fish in a barrel, people paying for their use of the Dartford Crossing remain subjected to an "alpha" site, which is apparently a "new" service. Four years after it went live. In what universe is going live with an alpha project a good idea, let alone still running it like that after four years??? Though maybe they're just being more honest than the rest of the govt. "digital" estate.
Apparently the gov.uk "brand owner" has no influence or control over this. You so couldn't make it up.
So good luck with MTD. You'll sure need it.
