So... what you're saying is: it's kinda similar to learning a new avionics suite?Mission+ is a decent EFB.
The problem is with human factors though. The way a 64 year old expects an application to work is much different than the expectations of a 24 year old.
Plus, it’s a lot like handing an iPhone user an Android. Like I have no clue how the Android works and the differences are interpreted as hindrances because of the learning curve, all which can be mitigated by, well, consolidating your skill by deciding to STFU and use it often. Any package will have a learning curve no matter what your technical abilities are.
Old dawgs, new katz, etc, etc... more buttons for no particular reason 'cept it's mo-betta kewl?
Learning is hard, m'kay.
