I enabled the editable grid control on a subgrid, but after publishing, I still see the read-only grid in the subgrid in classic UI. The grid is editable in unified interface. What’s up?

Chances are you have legacy form rendering enabled in your environment system settings. Disable legacy form rendering and your subgrid will be editable.
