Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
The property openingHours is listed in schema.org as a standard property and it should be validated unless it was incorrectly configured. https://schema.org/openingHours
I went ahead and inspected the affected URL in the official schema.org schema validator and it returns with no error as you can see in this screenshot in the sensitive Data section:
I also checked it using Google’s Rich Result Test and there’s no warning/error with regards to the openingHours property. See URL in the Sensitive Data section.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
Hi, thanks for your answer.
Just to let you know that semrush just confirmed this it’s an issue on their side.
So, nothing to do with rankmath or something else.
