On the home page of the app tap your account far right, then go to services and tap that and see what is says. Cam Plus should be shown, tap that to expand. It may also show your 14 day trial near the bottom. If you do not have any licenses available you will probably need to wait for the code to redeem the plus licenses. I got an email 7-8 days later with the codes. Or just call support 1-844-999-3226 M-F 5 AM to 6PM
