I’ve liked Phoenix a lot, and was excited for the splicing, but it’s actually proven to be quite a bit more expensive in my case.
I wanted to use Phoenix to receive via Lightning and then send to on-chain. With multiple open channels of various sizes, I had pretty good flexibility to both send and receive.
Now, when I send some of my sats to an on-chain address, I pay the miner fee (that’s fine) but it shrinks my channel capacity, so every next time I receive via Lightning, it reopens a new channel.
Basically I’m paying double the miner fees, every time I receive a substantial amount, because it has to reopen a larger channel, instead of using what I’d already opened.
I finally understand what’s happening well enough to articulate it (clearly, I hope).
Not sure what workarounds exist, if anything…
But re: taking forever to load, if you change to a different app (but don’t “swipe up” to fully close Phoenix) and then swipe back to the wallet it usually loads up on the second try.
