I've had independent Watch apps on the market for over three years now.
A continuing problem is that users will buy the apps from an iPhone, but if they don't have their Watch App Store setting enabled to "automatically install apps purchased from other devices", then the apps do not show up on their Watch.
This leads to daily support traffic with customers where I have to walk them through looking in the purchase history on the Watch's App Store app to manually install the apps on the Watch (I also tell them how to turn on the setting to enable automatic installs in the future).
I can't believe that after three years, this is still a major problem. It seems exacerbated by customers who don't understand the difference between companion apps and independent apps, and they often get belligerent, accusing me of ripping them off because the install didn't happen the way they expected.
Does anyone else see this problem as often as me? It has me contemplating pulling my Watch apps. The revenue is decent but I probably burn more $$ in time responding to these requests on a frequent bases. It also leads to a lot of poor reviews and angry customers.
