C.S.
I would get rid of the pull ups and if you daycare provider resist then get some underwear covers so there isn't a huge mess but she still knows when she wet.
I do in home daycare and I will let a child that is pooping in the toilet have a few messes, sometimes that is what it takes to get them to fulling recognize the have to pee sensation. But if it is more than one or two accidents a day I would say she isn't ready for underwear at daycare. There are a lot more distractions than at home.
