Still can not understand what I do wrong.

  1. New CTRL wallet created (on crome)
  2. 3 USDC and 1 ARB-ETH loded into it.
    Trying to swap USDC>> LEO
    It kepps pending, then - expires.
    Have tried that 3 times - always the same
    Was trying to swap 1 USDC >> 7.2 LEO

Do you have other wallets on chrome? Disable them. Try to have "Connecting priority" on CTRL wallet.
