Too new client, generally. I once tried Eclair and had instant 5 FC in a row. After them i figured out a proper setup but it was just a setup in my case.

Not sure on the FC. I heard it was something to do with HTLCs getting stuck and so you need to make sure you open up the wallet once every 24 hours to avoid the FC. But life got in the way for me and I had left it a couple of days. With that said there was no stuck HTLCs I was aware of so no idea why it FCd.

That was one thing, and I decided to give up on Mutiny for that reason. Was only using it for zaps anyway. For spending LN I'm using Phoenix and there are none of these kinds of issues. For zaps I am switching to WoS because it works and because the amounts are so small the rug pull wouldn't hurt so much.

But anyway this funds disappearing thing with Mutiny is a real concern because FCs are one thing and annoying, cost fees etc., , but outright losing funds I thought were self custodial is a different matter. I wonder if this kind of thing could also happen on Phoenix? If as Darth points out it's an LDK issue maybe any of these "non custodial" wallets that use LDK and LSPs could be at risk of similar bugs? Although like I said I have never had these kinds of problems on any other wallet than Mutiny.
