The way the menus for this new feature (that's quite helpful mostly) was done, it's crippled most of the time for anyone with a large enough city and map that scouts take 2 or more days each, and are almost always active.
The annoying and often erroneous pop-up "help" does show locked Province versus just active Scout status, including when ALL icons are greyed out. That's tedious and visually harmful (too much of Elvenar causes eye stress and long term physiological damage, that better use of color, size, contrast, etc could reduce - try mandating that staff volunteer for Wikipedia, which would reject much of Elvenar design). It'd work better to have a green/red or black, series of Scout icons that show locked or available status, and a global "Scout Busy" icon up top (since this is a simple function as to busy everywhere or nowhere, unlike many others). That way, when one has 50-100 or more Provinces in the Scoutable list, it'd be easier to identify which class each is in, and plan what comes next (including to add potential traders that aren't the incessant dead city coin mine problem, or harder to spot, just long since dead players). As things are now, absent hover over and trying to recall a hundred pop-up locked or unlocked messages, it's impossible to clearly distinguish status except in the brief periods between long Scout missions.
