Try this URL for the IDE https://graph-na02-useast1.api.smartthings.com/ @vlad reminded me that since you are a new user that you are on the new server NA02.
The likely reason you are not seeing them in the mobile app is that your account is actually on newer NA02 server while the app and devices were published on the NA01 server (I know confusing right 
).
Once you login with the URL above and add the app and devices again you should see them in the mobile app
