Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
This issue could suggests that the Rank Math cron jobs may not be running on your site on the scheduled time to update the cache. Please install this plugin and check whether this is the case.

I hope this info helps.
