I stopped using coinomi because I couldn't find where to get my wallet private key under settings and menu,they should have just make it easy like other wallets that reveals private keys,coinomi is very annoying maybe I will try enjin wallet out
You should be browsing coinomi more often. You can actually find your recovery phrase ( which is the private key ) in their settings, click the
show recovery phrase and input your password.
In there you can now see your recovery phrase and can import it to other wallet.
If you rely on your backup phrase what will happen if coinomi stop working?since you have no private key you won't be able to import backup phrase in all available wallets,only few like enjin supports coinomi backup phrases
