Sending ETH using the Manta Pacific Network

I sent $ETH from my metamask to my trezor twice and it took ~15 seconds for the transaction to be confirmed. The $ETH was sent via “Manta Pacific Network”. However, after receiving the Eth through the cold wallet, I can’t send it back to my meta mask and was pending overnight.

So, can I send & receive Ethereum (or any crypto supported by trezor) that’s on different networks and manage it via a third party wallet using trezor?

Thanks for the help.
