Hello,
Thank you for contacting us and we regret the inconvenience caused.
Assuming the property that you have is GA4, you’ll have to create a universal GA3 property to get that connected with Rank Math.
Since the API of GA4 is not matured yet, we do not support it. We have plans of implementing it once the API matures.
You can follow the guide you shared to create a UA property and then, head over to your WordPress admin area > Rank Math > General Settings > Analytics, and Reconnect your Google account.
Further, please check if the property is displayed in the dropdown field.
Please let us know how that goes.
Thank you.
