I didn't get my login code
A few things to check:
Make sure the phone number is entered correctly, including the area code. The app expects a US number.
Give it a minute. Text messages usually arrive in seconds, but carriers sometimes take longer.
Check that your phone isn't blocking messages from unknown numbers, and look in any spam or filtered-message folder your phone has.
If the code has expired (they last ten minutes), request a new one. The old code stops working once a new one is sent.
If nothing arrives after a couple of attempts, the team can look into whether messages are reaching your carrier.
