Hello,
Thanks a lot for your query and we are so sorry about the trouble this must have caused.
It appears the OneSignal Push Notifications
plugin you have enabled is causing this issue.
When it is enabled, the Rank Math’s SEO Meta box doesn’t appear.
Could you please confirm this from your end as well?
