It will fire for both of those if the feature includes an experiment
but yes, it should only fire when a feature is evaluated

I’m not sure about calling it twice for the same feature, I’d have to check the code to see if it checks for that
I imagine it may just fire it twice - what does it do if you run that?

we work fine with single page apps - is the feature not updating correctly or are you concerned about the tracking callback event?

are you targeting features that are page dependent? if so you may need to add a useEffect hook
