Problem

Bug report Having e-mail auth provider enabled gives a 429 rate limit exceeded, despite using only Phone auth provider. Describe the bug We had e-mail auth provider and phone auth provider enabled. (With e-mail auth not being used.) Once we started getting a spike in traffic for our SMS OTPs, we started getting a 429 rate limit exceeded, despite Twilio looking fine on our end. Once we disabled e-mail auth as a provider, everything was working normally again. To Reproduce 1. Enable e-mail and phone auth providers, 2. Try hitting rate limits that you would normally hit, but with phone SMSs, 3. Get a 429 - Rate Limit Exceeded. 4. Disable E-mail auth, and check that everything is working again. Expected behavior Did not expect any rate limit issues. System information - Browser: Chrome, - Version of "@supabase/supabase-js": "^2.1.1", - Version of Node.js: [e.g. 16.13.1]
