Hi, @Garima Singh
I was having this same problem, with Enpass crashing sometimes after entering the master passphrase or when trying to use the Enpass keyboard. The frequency of crashes raised throughout the last months after each upgrade, culminating in today's total failure when it started crashing while running in the background and then relaunched itself, just to crash again 5 seconds later. It wouldn't get out of this relaunch-crash cycle, so I had to uninstall it from my phone in order to keep it usable at all...
How is it possible that an awesome app, that worked flawlessly until six months ago with mostly the same features started shooting itself in the foot so fast (at least on Android)? I was actually considering to subscribe for the new premium features, but now I simply don't know what to do.
