I'm getting 10k organic installs per month. The people that stay become daily users, but way too many leave right away.
7 months after launch and I realized I'm using a qzz.io domain for some of my backend operations and after running some tests I realized many wifi routers/DNS block it. I had 30-40% of my users that couldn't use the app!
Lesson learned! Just a heads up so you don't make the same mistake as me
