Thanks for the response. It is indeed an ETH transaction. I couldn't much information either. If it is the reason you mentioned, is it something that I can try to fix? Or just wait?
Which means it is an ERC20 token transaction.
You have not broadcasted the transaction at all, but when you want to broadcast the transaction, it brought up the error. If it is like that, that means you need to send ether to the ether wallet address on your Coinomi wallet be able to cover the fee to make the transaction.
In every ERC20 token transaction, ether is the gas fee that would be deducted. Send ether that would be enough as fee to the wallet. After, you will be able to broadcast the ERC20 token transaction and ether would be deducted as fee.
