I have canceled my pixiv Premium membership, but I can still use the Premium features even after the next renewal date (termination date)

If you cancel your automatic premium renewal via an external service other than pixiv (App Store, Google Play, etc.), there may be a time lag of 1 to 3 days before the cancellation takes effect.

You can still use pixiv Premium during the time lag period, and please rest assured as you will not be charged after the renewal date.
