Hello, I have a question, how can I update a values other fragments, for example i have an app that can save some tasks, so i have one fragment to show tasks and another one to set and save tasks, but fragment pages do not refreshed or reload so it problematic to me, to show the added or updated data instead of just switching fragment I am turning off the app and turn un, so how can I solve it?
Hi there i used your tutorial and it works perfectly but im facing the issue that it seems to override my start activity which is my login activity and launches this bottom navigation activity first each time. Is there any fix to this?
I was stuck with the problem of switching the fragments when pressing the bottom navbar items but when i set the same id of fragments in my_nav and items in bottom_nav (menu) it runs succesfully.

Can someone help me? I have the exact same code as the video with, the only difference is that a fragment from a nav_graph to an another activity (HomeActivity) with another (surely in the future) nav_graph navigation.
