On the parks that have tiered FP+, I have made my three FP+; one for tier 1 and two for tier 2. Here are my two examples which leads to the same question.
Example one, I make one of my tier 2 FP+ early in the day and I do not use it and it expires. I use my other two FP+ as reserved. After using my last FP+, can I go to a kiosk and attempt to get another tier 1 attraction?
Example two, I use my two FP+ (tier one and one tier 2) as reserved. I then cancel my other tier 2 FP+ before the time of the reservation. Can I immediately go to a kiosk after cancelling the tier 2 FP+ and attempt to get another FP+ for a tier 1 attraction?
