Does the Apple Pencil work with zagg glass on the screen
Will iPad pencil work with zag screen protector
Pencild
I have no personal experience, but others on the forum have said they've used the pencil with a screen protector with no issues.
You could check but I believe zagg has a 30 day 'no questions asked' return policy on their stuff. If I'm right and they do (please double check that) then you'd have nothing to lose but time and return postage if it doesn't work out
