What happens after subscription cancellation?

As the game is currently not playable in a fun way because it is super laggy, I consider cancelling my subscription.

What will happen with the account including the grade? Maybe, if someday the performance improves and picing is not going crazy anymore, I would consider having a subscription again. Will the same grade be available them to?

Thanks.

Your grade is tied to your account, you can cancel your subscription and resubscribe anytime, your grade will not change (unless you’re grade 4).
