I'm sorry for the confusion this has caused. I would like to confirm that these to charges are verification charges on your credit card. You will need to verify these amounts on your Upwork account before you can use your credit card as a billing method. You may read more about it here for more information.
I will go ahead and share your account information and these screen grabs with the Customer Support Team so that they can reach out to you to assist you further.
I am using a visa card and iam getting similar meaasge when i trying to buy more connects it says"We are unable to authorize your card. Please add another billing method or contact your issuing bank."
