mapStores and nested components

[plweil]

I'm using mapStores() in my root-level component, but I'm finding that I need to map one or more of these stores again in some of my nested components. I thought mapStores() would work for all nested components. What determines when mapStores() will no longer apply to a nested component? So far I've been using trial-and-error, but it would be helpful to know when I need to map relevant stores a second time, or what I can do to have an initial mapStores() work in all of my nested components (we're talking about maybe 5 nested components, not dozens).

Related question: can someone please verify whether using mapStores() should mitigate the need to use mapWritableState(), or do I need to apply the latter explicitly whenever I need to write to state properties? My initial experience suggests that I need to use mapWritableState() regardless.

I have the same question. I was hoping to use the mapStores() in the root component and somehow provide it from root and inject the store into the child components but that doesn't seem to work. Any ideas @posva ?
Thanks!
