Not sure what is the correct technical term, but when I was changing a component in my previous nextjs (v 14) the browser quickly received the update without a full reload.
After upgraded to 15.2.3 and using this for dev development: next dev --turbo --hostname 0.0.0.0

I do not get the change in components detected anymore and page doesn't reload the component, nor it does a full refresh. In fact, if I change the layout.js (app router) I see a new message in the terminal saying Compiled (so change gets detected) but the browser doesn't see the change. I changed something obvious like body background color and I only see the change after I manually refresh the browser.

So:
1. layout change -> terminal shows the change is detected and recompiles -> but browser doesn't reflect the change
2. component change -> neither terminal nor browser react to change.

I did try the same with a newly created nextjs 15 project, and it works in fact.

also attached my app structure.


so something from my project, prevents the change detection to work.

How do I go to debugging and fixing this?

PS: I do not want to go back to nextjs 14.

Thank you!
