I have a reflection probe in the scene which I would expect to affect my chrome ball. But it is not. What is wrong here?
EDIT: it seems that the box size was too LARGE…? very strange, but with 5x5x5 it works… with 100x100x100, it doesn’t…
A lot of things in Unity make little sense to me these days, some explanation would be appreciated 
Only thing that comes to mind is maybe Reflection Probe are disabled in your HDRP Default Settings and/or Camera Custom Frame Settings ?
Or maybe you reached the Maximum Reflection Probe On Screen (defined in your current HDRP asset under lighting) ?
maybe dumb question but did you have baked the reflection probe?
It may not be affecting that sphere because of probe layer mask.
