Auth completely down in production.

Hey Supabase team,
Auth is completely down in production. I’m using Supabase-hosted (not self-hosted), and starting from tonight, all users are getting logged out and getting a 400 | refresh_token_not_found error on /auth/v1/token.
I also started seeing 500 errors before that, and I didn’t change anything in the code or Supabase configuration recently.

Here’s what I tried:
• Checked logs — all token refreshes return 400 or 500
• Tried creating a new user — even that fails now
• I did run DELETE FROM auth.sessions and DELETE FROM auth.refresh_tokens once, but the issue was already happening before that
• The issue persists on new installs, new users, and all iOS devices tested
• Everything was working perfectly before — the app is live with paid users, and now auth is fully broken

Is this a Supabase-side issue? What can I do to fix this ASAP?
