Hello again,
The solution I provided here above is just a workaround.
But I saw here and there some more appropriate (hivepress’) ways to implement this way of knowing which package the current user is currently having, using User_Listing_Package::query().
My point is I would like to conditionally enable special extra features like multi-category select, depending on current user package, but I am stuck, right now.
Could you please help me with that ?
