I have an account with Steady because I was able to sign in using password and email address. Then get to the part where it asks for phone number and that's the phone number I have signed in with, but it won't let me sign in. Keeps telling me "phone number already exists or is invalid". Well, of course it exists! It's the one I use. And it's valid. Not invalid. I had that problem several months ago and it was the reason I uninstalled this app. I try again and I see it's still not been fixed!
