Regarding Renewal for PRO Subscription

I am a long-standing user of the Rank Math SEO plugin. I am reaching out to inquire about a recent discrepancy I noticed concerning the renewal price for my PRO subscription.

Over the past couple of years, I have been consistently renewing my subscription at a reasonably stable price point. To show, my previous orders were as follows: July 4, 2021, and August 4, 2022: $59.00.

However, I recently attempted to renew my subscription and was surprised to see the price listed as $81, which is significantly higher than my previous renewals.

I would appreciate it if you could provide regarding this price change and whether any loyal customer discounts or legacy pricing options might be applicable in my case.
