Hi
You have a couple of options for training,
Their you tube channel channel a lot of info, just remember the free version is the "Express" version, so looking at the other (Paid) versions will show you different functionality
The next option is their paid training classes you can find here:

Or you can ask your partner to assist with training if they have someone who has the skills
Cheers
