thank you so much for replying....my iPad is upgraded as far as it can be upgraded. I appreciate your help....new iPad I suppose!!

You're welcome.

FYI, the latest iPad supports Apple Pencil

Safari is a part of Mac OS and iOS so the only way to get the most current version is to upgrade that version.

Your device may be too old to upgrade it's iOS version so you're out of luck.
