Hi, I have a player MVI that seems to have trouble receiving labels from the store.labels flow labels quickly after creation (nothing gets emitted from store.labels) - I was wondering if the labelsChannel is the best way to go and i guess i should bind manually and not use the standard Binder? is that the recommended way?

Most likely labels are emitted before the subscription happens. In this case labelsChannel won't help either (it's designed to not miss emissions while the app is in background or the screen is in the back stack). Most likely you need manual init. See "Initializing a Store" here: https://arkivanov.github.io/MVIKotlin/store.html

yeah it seems to do something just by switching to labelsChannel i seem to get the missing labels (commit below) - i guess the channel must be buffering the labels. though i guess the labels channel will emit anything unconsumed if I reconnect to it (i.e. go out of and return to my activity)?

but now i see your docs on autoInit = false in the labelsChannel

do you think its best to do manual init and use the flows? or use the labelsChannel? i guess either is good

If you receive labels via labelsChannel and don't receive via labels, then probably there is something else. The channel is only created when you call labelsChannel() function. It's actually supposed to be called right after the store creation. Calling it a second time will create another channel.

In your case, I think it's better to use manual init. The flow is usually as follows:

1. Create a store
2. Subscribe/bind everything
3. Call init()
