[Spider-Verse] Why couldn't Gwen tell Miles had spider powers?

The first times Miles and Peter Parker / B. Parker met they had moments where they sensed each other's spider powers. Why didn't this happen when he ran into Gwen after being bitten?

We don’t see her sense it but when Miles literally runs into her after gaining the powers and he’s stuck on her hair what she’s telling him to do to unstick is the same advice that Peter B gives Miles when he can’t unstick later. 

I think she knows or at least suspects at that point. Then she sees him on the building walls later and knows.

We might not see the sense go off because Miles spider sense hasn’t kicked in yet. He doesn’t get a warning until just before Green Goblin shows up. As the person we’re seeing the universe through he wouldn’t see her sense so we don’t. 

Or perhaps it’s the two senses interacting that lets them know. We always see both go off at once. If Miles danger sense hasn’t kicked in yet then there was nothing for Gwen’s to hit.
