I’m spraying latex for the first time. The can says the paint wil dry in 4 hours, does that change when you spray it? It feels dry to the touch within minutes already. Weather today is 50% humidity and 75 degrees, if that makes a difference.

What does the can say about dry-to-touch time and recoat time? Very different sometimes.

re-coating too son can do several things to compromise the finish.
If spraying, yuou can deny the first coats access to the oxygen that may be needed to cure hard. You do want a strong long-lasting job, don't you?
When rolling or brushing, your tool can grab the top surface and peel it away from the uncured underbody of the fiolm, pulling it away from the wall and mixing it in gobs with the new coat you are trying to apply.

Let it dry at least 4 hours. As the others have said, just because the surface 'feels' dry, doesn't mean the paint film has set.
Spraying paint dries it out on the way to the surface, so in this case,, feeling is not believing.

Depends how you're spraying. I use HVLP and the hot air makes it dry very very fast. Airless doesn't change it all that much, but as the others have mentioned better to err on the side of "too dry". And check if it requires sanding between coats.
