Sent some on-chain satoshis from Electrum to my Muun wallet at 4.1 sat/vB about two hours before time of this post. Then I attempted to exchange sats on lightning network using FixedFloat with abnormal LN fee and then to see message "This payment is waiting for an on-chain confirmation." Technically the satoshis are not sent off yet (money on hold) but the sats are deducted. FixedFloat will forget your transaction after 30 minutes and so if sent way after 30 minutes, my money is sent to the void. Will Muun cancelled the pending LN transaction after 24 hours or will it stay like that until on-chain fees are low again. If the latter, have my money gone to the void? Need some clarity. Thanks.
