Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
The .html or .aspx are redirecting fine upon testing. You can also refer to the screenshot attached in the sensitive data section.
Could you please check this one with your web host if they are serving .html
or .aspx
URLs which may prevent the redirects from Rank Math?
Let us know how this goes.
Thank you.
