After signing in, go to the "My Venue" tab on the left hand side of the business portal. Once there, you will be provided with a 6 digit code. After downloading the Loop app, you will be prompted to enter this 6 digit code and claim a screen.
If you'd like to add another Loop TV to your business portal account, just click the small plus sign next to Loop TV, give your TV a unique name, and repeat the process above.
PLEASE NOTE: if you add an additional Loop TV and would like to access premium features, you will be charged a monthly rate per screen for that premium feature.
