Can't send phone number to get code?

Hello

For the past few weeks I haven't been able to login. I fill in my phone number, but clicking the "send code" link doesn't do anything. The only reaction from it is prompting me to accept the Terms and Conditions if I haven't checked it.

This happens on Firefox and Edge and Firefox mobile across three different devices, and even on Kimi desktop.

Anybody's seen something like this before or has a solution?
