I had this same issue that’s why I was confused lol

Yeah, that might be what's happening. In Mutiny, if you select the pending transaction, it'll show you a pop-up with all the transaction's information. Click on the link at the bottom next to "TXID", and it'll take you to where you can see your transaction in the mempool (be sure to scroll down and click on "see more details"). That way, you can verify where it is, and get a good idea how much longer it'll be until it's confirmed.

I have the similar issue and cant Transfer my on-chain funds. After closing the channel I see in the pop-up the following text "Channel closed because of an exception: closing_signef negotiation failed to finish within two timer ticks". I can only see the channel ID, so how can I get more information about the transaction?

Mine went thru 👍
