How long does it takes for your add-on to be reviewed and to show up in the add-on store after you submitted it?

I recently uploaded an add-on through the Add-on Developer Hub, my add-on (extension) got approved with zero issue but I am still not able to see it in the Add-on store. How long will it take to show up ?

If you’ve uploaded it as listed, it should appear immediately (with a link also available in your submissions list to the listing). However if you uploaded it as unlisted/self-distributed (or using web-ext sign) it will not appear publicly. You would have to upload a new version and make sure you choose the correct distribution type when uploading the version.
