Since others are already helping you with your first question, I'll attempt to answer your second question. What kind of information are you looking for? Are you looking for information on how Qlik Sense can be used within your organisation, or are you simply looking to get better at creating applications?
For the former I think others can give you a better answer than I can, but for the latter:
- Browse these forums regularly and have a look through the questions and answers posted by others, even if the answers might not directly be something beneficial to what you're currently working on. After a while, you might even be able to answer some questions which can really help in training you to become better at app development. Note that a lot of Qlikview posts will also apply to Qlik Sense, especially when it comes to scripting, so don't limit yourself to the Qlik Sense pages.
- Read through some community blogs to learn about Qlik Sense's (/Qlikview's) possibilities and features. I personally find hic's and jmc's blogs particularly useful (If the links don't work, just type their names in the search bar, press enter, and filter by type of post = blogs.
These 3 options are pretty much how I learned what I know about Qlik. I'm by no means an expert and I still consider myself fairly new to Qlik, but I think that is mostly because I haven't been using the software for that long. Hope this helps! 🙂
