I just started beta testing the 2.0 update to the billing library for the Play Store and a lot of my users are getting this error Google Play In-app Billing API version is less than 3
.
Is this just a matter of time before they update or are some devices stuck on older versions or what?
I started seeing this error when using the Emulator without logging into Google Play.
Once I logged into Google Play with my account the error went away.
