Hi, Post is dead, but it is on the first page of google when you type “acf cron get_field options page”, so for future seekers, there is a solution.
I had similar problem. I can’t get fields values by get_field in function fired by cron. So, after research in acf and polylang code I used:
$locale = 'en_GB'; // You can use get locale function, for eg from polylang: pll_get_post_language( $post_id, 'locale' )
get_field($name, 'options_'.$locale);
instead of
get_field($name, 'options');
And it works.
