Gmail Notes disappeared after iOS update!

I recently updated my iPhone to iOS 16, and when I went to Notes, I noticed that all but one of my Gmail Notes are no longer showing up on my phone, despite the fact that I've always had Notes synced to this Google account. I checked my email (because Notes usually show up as a label there, too) but the same thing - all but one are gone! Is anyone else having this issue? I've tried reaching out to both Apple and Google (how the **** do you talk to a REAL person!?!) and have heard conflicting information whether this is an Apple issue or a Google issue. Has anyone else experienced this? And, if so, do you know how to get Gmail Notes back. I had some really important Notes that I'd hate to lose!
