I’m sure there are others there selling themes that include ACF, maybe ask them what they do? Or ask the people in charge there?
I’m not familiar with Themeforest. I am a little familiar with the theme check plugin and I know some of the things it does not like. The biggest one you’ll have to overcome is the one I mentioned above. The function call for file_get_contents(); throws up a big reg flag in theme check and doing a lot of digging I discovered that there isn’t any way around using that function without completely defeating the purpose of saving fields groups in local JSON files, which is reducing execution time.
