When it's grayed out it means that the tx is not yet confirmed, that's not a Coinomi issue, though, and it would be unwise to try to spend an unconfirmed output.

Coinomi is not going away any time soon, however just to keep your mind in peace, all you need to gain access to your funds at any time is your seed phrase.
