I have checked multiple apps, and in most of them, bottom navigation is only visible on parent activities, when i go in any inner activity bottom navigation goes away, so my question is that is there any guideline regarding this available in material design, or everyone is just following this approach without any proper guideline,
and is it a right approach to have bottom navigation only on parent activities.
and in which cases we hide navigation on child activities, if not in all.
For example, i have an item in navigation
Team, when user taps on it i open Team Screen, which contains 5 items, so when user further goes into these items i disable navigation, is it the correct approach?
