I completely misunderstood that app until now. I realize now that their fees are based on memepool predicted fees. I zapped 1000 sats and got hit near 8000 in fees (and it won’t ask if it’s ok). Later I tried to move 10,000 sats to try a Phoenix wallet and the fee was so big (131,000 sats) that it wouldn’t do it bc i lacked funds.
