I need to sort this out because it's a pretty big problem. My users keep sending emails that they can't install the app because an error code: -2. Here's a screenshot I received.
Do you have any advice? Thanks a lot!
UPDATE: Looks like after an app update the problem got solved. Users reporting install now works.
Maybe it's not a real solution but I had the same issue days before. After several days searching in the internet I updated my app in Play Store with some minor changes (nothing that really helps to solve this error I think).
The error simply dissapeared. Maybe is just a Google Play bug. So if you are planning an update just do it and I think it will be solved.
