That is interesting, thanks for the info!
I used https://boltz.exchange/swap. It has worked well every time. From lightning to liquid is a little more expensive than liquid to lightning but still not an unreasonable price.

No problem. Boltz has been a good swap option so far. I'd recommend spending a bit of time really being clear about the swapping of on chain btc to lightning though if you ever use that in future. In particular with that on chain to lightning swap be aware of the fee that is selected and how that will/might be important in how long the invoice that you've generated is valid. If the fee is low( longer blockchain confirmation) then if the invoice has already expired then there is a 24 hour wait and a little bit of sweating to get a refund through. Above doesn't apply to liquid<> lightning swaps though.
