Bug reports when bridging sUSDT to USDT and USDT to sUSDT the first and second transactions have quite a long delay

I bridged sUSDT to USDT and USDT to sUSDT 2x each. The first transaction when I bridged sUSDT to USDT I got quite a long delay, but I think the second transaction was quite instant or very fast. And the second is when the USDT to sUSDT bridge is first I got a fast processing time, but for the second transaction I got another delay, I hope that in the future these transactions can all run normally and fast. thank you for this valuable experience, I really support the team.
