Simulator says I need a newer version of Expo Client -- but am I even using the Expo Client if I have detached to ExpoKit?

Expo SDK
2

My solution was to un-detach as described at https://docs.expo.io/versions/latest/expokit/advanced-expokit-topics

And then I upgraded to SDK 28. Then I detached to ExpoKit again. Now I’m able to run my app in the simulator.
