Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
As of now, it seems like only a handful of users are affected by this issue. We are unable to replicate this issue from our end but we have contacted Google about this and will have a fix very soon.
This is happening because the plugin outgrew our API requests and we have requested Google to increase the quota asap.
We should have a fix ready within this week and will release an update.
Again, extremely sorry for the issue you are facing and we seek your patience and understanding in this matter.
In the meantime, if there’s anything else we can help you with, please do let us know. We are here to help.
Since we did not hear back from you for 15 days, we are assuming that you found the solution. We are closing this support ticket.
If you still need assistance or any other help, please feel free to open a new support ticket, and we will be more than happy to assist.
