It looks like they've abandoned the project but left some existing servers running.
They are still a bit active in Coinomi Official Telegram, they posted about Coinomi web wallet, so they are still working on something, but I don't see much activity on twitter and other social media.
I wouldn't risk using them anymore when there is solid open source multicoin alternatives like Unstoppable.money wallet or Komodo wallet.
They even have swap exchanges integrated that works much better than in Coinomi wallet, but I don't think they support monero.
There is one more less known mobile wallet that supports Bitcoin with monero and other privacy coins, and it's called Stack wallet, but use it at your own risk:
