Binance Wallet's professional mode has many bugs, it's a real pain. I submitted numerous buy orders around noon, all of which failed. Besides showing that the order was submitted, there were no other functional prompts. Another time, an order was submitted but hadn't been completed for 40 minutes, it was stuck. I finally had to contact customer service to resolve the issue, but by then I had missed the optimal entry point. I hope our testing team will give it a try; this mode is indeed very difficult to use. @BinanceWallet
