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 '⚙️'.
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.
