Their subreddit paints a similarly bleak picture: https://www.reddit.com/r/coinomi. Lots of posts of people being unable to spend coins, unable to sync, getting a variety of error messages. The comment section for each of those posts is just filled with spam.

Also no activity on their Twitter accounts for over a year.

I would say it's a good result all round that the wallet has collapsed. A closed source wallet which sends seed phrases over the internet in plain text to Google has no right to continue to exist. I would suggest everyone uses their back ups to sweep their coins to a better wallet.
