Publishing apps - why do they make it so frustrating?

I'm currently going thru the process of publishing a series of Android apps that we've been developing for awhile.  We have decided to monetize the apps with:

• InApp Purchases
• consumeable features
• subscription based features
• AdMob banner ads
• small (50x300) banner ads at the bottom of each page

We also have extensive experience publishing apps to the Windows Phone Store and thru the Windows 8 Store, both of which have since been combined and renamed.

So, once upon a time (before I had published my first app), I had thought that, "hey, I'll just submit my app to the store and the bucks will start rolling in."  In retrospect, that has not yet been the case, but I'm still working on getting the right apps to the right users.  In the process, I have seen some similar frustrating factors that enter into the publishing (and maintenance) of each app that I naively did not expect to be a part of the publishing process.
