Per ACF Pro Support’s suggestion (after a user in the other forum linked to here since support's reply didn't have a link), I’m posting this request here (I know this is a long shot).

Currently, the ACF Pro License only recognizes the string “stage” or “dev” in the domain name to automatically deem a particular site to be considered staging or development, which would not count against the valid license meant for production sites.

In my situation, I have a production site that uses http://www.mysite.com and an established staging/development site (well before ACF Pro License started recognizing staging sites) that uses devel.mysite.com.

However, I’m still forced to use my devel site as my production site for my lifetime license due to the very specific and restrictive “dev” string they’re looking for.

Therefore, I’d like to see the requirement expanded to include the string “devel” in that automatic development/staging site detection (or at least “dev is a wildcard).

That way, there’s no need to maintain yet another development site or having to switch licenses between production and devel site just to satisfy this very specific and restrictive requirement.
