This is a big issue for me and many other Power BI Developers I know.
Some form of developer licensing is required as currently we are unable to learn/test many new features that are restricted to Premium only. As it stands the price point for Premium is too expensive for most medium sized businesses.
Trying to convince them of the benefits vs costs without being able to produce demos for them is problematic.
Thanks for the suggestion! That sounds really useful, if anyone else agrees please add your votes!
