Not seeing the green "checkbox" after adding your Simple to your cloud account? Try the steps below.
Navigate to the "Password" section of your LCD menu. Go to "Settings", and then "Password".
Leave the "Password:" field blank and tap the checkbox at the bottom right of the LCD screen. In some rare cases, you will need to type in a character (for example the letter A), then delete the character, and tap the checkbox at the bottom right of the LCD screen.
Log in to your printrbot.cloud account and edit the recently added printer.
Leave the Password field blank and re-save the printer.
These steps will communicate to your Simple that no password is required and get the cloud and your Simple on the "same page". You should now see the connection status for your Simple on your cloud account.
