Follow these steps if:
a. You created a 'web browser based' display or other display and now want to move/assign it to a different physical device that is running the Mango Display App
OR
b. The same physical device (example Samsung TV) had an app or system update and is now displaying a Display Device Code instead of your layout when the Mango Display App is launched.
Login to your account at https://app.mangodisplay.com.
Click on the display you want to edit.
At the upper right corner of the screen click the Settings icon 'βοΈ'.
Then select 'Display Device Code'.
Type in your new device code on the line provided.
Click 'Update' to save your changes and you're done!
*Note that due to potential differences in screen size and resolutions between the the two devices, you might need to adjust the layout accordingly.
