you are only required to settle the 'statement balance' - all transactions posted by statement date
so it's unlikely that your 8 Feb transaction will be posted by 21 Jan :lol2:

you may settle the 'outstanding balance', inclusive of the 8 Feb purchase, but you will not be charged if you only pay the statement balance by 10 Feb

statement date is 21 Jan 2023. So you need to pay for all transaction before that date on 10th Feb 2023.

When you buy on 8 Feb, this transaction should appear on the following statement e.g. 21 Feb 2023

Anyway, your statement cannot see? Just pay the outstanding on your statement is good enough.

Statement Date: That PDF email comes to your email inbox, indicating that's your monthly usage with X bank's CC.
Payment Date: XX/XX/XX is the F I N A L day to make payment to X bank before they charge you charges.

Throw Apple or ANY MERCHANT out of the question. Item on your hand or not, X bank does not care.
Your statement shows Apple already charged you RM6,000 right? Pay it off. Why? Refer the above sentence.

Pay before 10th Feb 2023 (to be safe), you pay RM6,000 nett. No extra charges what so ever.
Pay after 10th Feb 2023, bear the finance charges from 15-18% depending on your CC and bank.

There's no need to complicated things.

Just pay according to the statement that you received.

If your statement usually on the 21st day of the month, usually by the next day the statement should already emailed to you for payment.

The 20 days (22nd-until-10th) is a grace period by the bank for you to pay according to the what the bank had sent to you.

If the statement date is 21st, the last transaction to be included in the statement is those performed on the 21st.

Transactions made on 22nd (or on 8th the next month) will be reflected on the next statement.

TL;DR-

Transactions made on 8 February 2023, will appear on 21 February 2023 statement, which due payment before 10 March 2023.
