Hi there,
Thank you for getting in touch with us.
I have run a few tests on your site on a mobile device and it appears that the following attributes are being altered onto the Google API loading script tag which is most likely the cause of the issue: type="rocketlazyloadscript" data-rocket-type='text/javascript'
With that said, please may you disable WP Rocket on the pages that you display a map and confirm if this resolves the issue?
I look forward to hearing back from you.
Kindest Regards,
Matthew
