I’d like to make sure we’re are all on the same page, so let’s quickly run over the basics:
In order to use a customized (professional version) of Resco Mobile CRM, you need to have a mobile license (a license for the professional version of Resco Mobile CRM).
A mobile license is not to be confused with a Microsoft Dynamics CRM license.
2 different things.
A user can log into Dynamics CRM via the mobile app using his/her existing credentials, however without a mobile license, he/she will only see the out-of-the-box version of the app, not the customized version of it.
