The transactions shown in the images you shared have been made from your trading account, not your wallet.
I haven't ever used blockchain.com trading account and I don't really know how it works. I just know that KYC is mandatory in blockchain.com trading account. Have you verified your identity? That may be why they haven't processed your transactions.
Contact blockchain.com support and ask them why these transactions haven't been processed. They have full control over trading accounts.
Exactly, and I guess that must be the reason why the transaction hasn't been processed.
It's unbelievable that transactions will be delayed that long, as I'm sure even transactions with a 1 sat/byte fee will be included in the block when the fees drop. Obviously something happened to the transaction, and it's likely that the OP hasn't done any KYC verification for his blockchain trading account.
