The transactions are send with a low fee. You’ll have to increase the fee on the first transaction instead of sending a new one like you did now.
Using increase fee with the Leather extension is broken with Ledger so you’ll have to create a new transaction and then edit the nonce before you confirm it. The nonce should be 0 STX, I think if you use a fee in the range of the last block 0.1-1 STX for a STX transfer it will get processed normally.
You can edit the nonce by clicking edit nonce above the confirm button and then setting it appropriately, first transaction for your address would be 0, then 1, 2, etc. You can see them here if you inspect your address and the pending transactions on it on explorer.hiro.so
