Derailed and specific instructions on features and how to use them. I have run into things that I have been unable to find specific instructions for through the articles and tips. Things like should you leave portal on all the time, why does screen shift from wide full room view to narrowed focus view on its own and how to control it, why does it change from full screen to a strip in the middle of the screen arbitrarily etc. trying to glean through the “tips” yields no answers. Specific detailed instructions and manual similar to ones that come with most technology products would be very helpful.
