reactInstanceManager is no longer supported in the new architecture. We could expose a currentReactContext on ReactDelegate if that would help you migrate?

Is there any way to get reactContext in MainActivity.kt in 0.76.6?

[fgedlek]

@saikrishnanamburi @chenvvy you can get the reactContext from reactActivityDelegate.reactHost.currentReactContext - works on version 0.76.7
