This is a publication issue!
I've made my app, and I've published it on the Google Play Store. Problem is, whenever I want to update the application, it works fine, but I've noticed on my clients' devices that the app doesn't automatically update. Instead they have to uninstall and reinstall the application in order to receive updates! This really isn't ideal, because my app frequently gets new features, and I would like my users to receive full functionality available without manually having to uninstall and reinstall the app! What should I do?
Thanks in advance, YomanAwe
