Hi there.
Actually, I had a similar problem when I launched my digital product 3 years ago.
I co-founded my startup and since then (September 2015) I'm working on creating, implementing and analyzing my marketing and sales.
My specialty is analytics. I have experience with Facebook Analytics, Google Analytics, Unity Analytics, Firebase etc. So, I think the first thing we need to do is to identify where are the problems and what we can improve.
I would like to check the current situation and after that, I can tell you what we can improve and how to do that.
P.S. ---------Karting---------
