Potty training tips for stubborn kids

I need all the tips I can get at this point. Our girl is sooo smart she is 3 but still not potty trained. And I am at a loss. I have potty trained two kids before her and had no problems.

- she knows what a potty is, and how to use it.

- she has gone poop and pee on the potty several times. We used the reward method after. All potty experiences were positive.

- she knows when she goes, she hates being in soiled diapers.

Here’s the kicker, she literally tells me no she doesn’t want to go to the potty. And more times then not she will hold it and then go afterwards.

The only time she is down to go on the potty is bed time because she doesn’t want to go to bed. So I have a feeling it has to do with she doesn’t wanna stop playing to go on potty.

Do I just need to wait longer and try again?
