Is this happening on Old or New Architecture?

| "newArchEnabled": true
This problem also persists when rebooting and launching android without Expo Go
I also want to add that if we want to set the input height manually via useState or useSharedValue, then onContentSizeChange will stop being called when changing the number of lines inside the input field

When can you decide? Is there anything else you need to provide?

I’m facing the same issue. The only difference is that I’m modifying the height of the parent View component instead of the Input directly.
