Hello again, running into an issue trying to combine live data as flows.  When updating livedata objects I am not seeing the combine trigger.  Example in thread

```val flow = combine(first.asFlow(), second.asFlow()){ first, second ->
    first to second
}
...
fun updateFirst(update: String) {
   first.value = update // combine transform is not called
}```
I am observing the flow object in my compose screen

What is the `first` and why do you think it should emit data to flow?

```val first = MutableLiveData<String>()```
Sorry first is a livedata object that is changing

Should an update of that livedata invoke the combine transform in this case, or am I doing this wrong?

combine first needs values from all flows before it can transform. I think the Livedata you are passing contain nothing, so they are not emitting.

It is also possible that you are not collecting/consuming the flow, so it isn't subscribed to any changes.

I am collecting the flow in my screen, but I suspect its an issue with your first observation.  Thank you, I will check there
