I see. I don't know of any wallets that aren't affected at some point by network congestion.
This is not a flaw in muun wallet per se then is it?
Discussion
Any real lightning wallet should be able to work under any fee circumstances
Some nuance to that but Muun uses submarine swaps and doesn’t actually have real channels in the wallet
A lightning wallet shouldn't have issue to make transactions during on-chain congestions because that's exactly why they are made for: be able to make instant transactions with very low fees without carrying of the on-chain network congestion/high fees. But muun is not a full lightning wallet, they make submarine swaps, it's more like a on demand lightning service, so when bitcoin network is congested is unusable
Thanks for the explanation amigo. I had heard about submarine swaps but never fully understood them.
