According to what help page says, yes you are correct @Daniel_Armstrong. However, it also depends, on how many devices that your users are using these apps. To the best of my knowledge, I know that there is a limit for that also. I mean you can have 1 licence but you are not allowed to use that licence with 10 different devices. And if you exceed that limit, although it’s the same user, the exceeding limit is countified as a licence. It could be a good idea to send an email to email@example.com rather than posting it here, as it might be lost in billion of messages.
