Been using Hangouts on 1 year old Fire perfectly. Now forces me to Chat app instead but like other reviewers here said Chat will not open on amazon fire so is useless and I have to use competitor apps instead. App was not tested sufficiently before release. Let people continue to use Hangouts until you fix it or you will lose more users. Update : thanks but I did system update, forced stop, clear cache (not avail), uninstall and reinstall before posting. None of that helped! Fix your app!
