How's the in-screen FPR working with screen protector?

Mine works good with the Zagg but best buy messed up the install and theira a little tiny circle of dust and he saw it and said I could bring it back they didn't have anymore. Husband hasn't even set up his phone yet but he thinks his is to to high to where when you show down your notifications is going to interfere I don't know. But I like Zagg and we got them free using PayPal and Amex reward points.
 
They are not semi permanent. They glue peels easily. Plus I have never had an issue with glass and the finger print reader.
I've never had an issue with the glass screen protector registering my fingerprints either.
