My Question or Issue
Hi, I would like to bring it to your notice that authorization flow is broken for login with phone number. It throws this error - Missing client id. Well, the same piece of code works with log in with email or Facebook. I was able to replicate the issue on this web app (based on Spotify API) - http://sortyourmusic.playlistmachinery.com/
Also, I faced the same issue on a Spotify API based project I am working on currently.
Kindly find the attachment and fix the issue with authorization flow.
