Can no longer see my phone summary when connected to computer with USB cord that previously showed it.

What would make it dissapear and how do I get it back? It's still checking for uploads and asking if I trust the phone, but it's not showing up on iTunes like it always has. Cord is still charging fine.

Phone is a 7 Plus, if this helps after recent iOS update. I can't tell if it's syncing wirelessly, but it usually does daily.

How can I fix this so I can monitor it in iTunes as usual?

Thank you!
