My first experience with Dynamics 365 for Financials:
Sign-up: I have had to sign in three times to be able to reach the main screen of project Madeira (sample project) in Financials space. I do not know if it was the creation of the space or the sign-in process what failed, but after that I entered into the main screen.
First navigation: It’s easy to find the resources and the sample data enables you to build an idea about how data is organized. The set-up of the environment can be done manually or in an assisted way.
After 10 minutes it has crashed, and I have started it again now not in IE navigator but using Firefox. Ironically with Firefox the navigation goes better.
