Ionic V1 - Native Facebook Login Hash Key not found

I am using the native facebook login ( plugin for my ionic app. I can successfully login, close the app and then log back in without storing any keys or app ids in my application backend. however, if I delete the app and reinstall same APK, I get the hash key not found error. I am using a production build and installing it from an outside app store (i.e. my Google Drive).
