Same issue here, iOS 10.2 iPhone 5S, Premium User. What can I say? So annoyed about this. Rebooting didn't work so now trying the reinstall route and the long wait for notes to sync. I am amazed how a comapny repeatedly shoots itself in both feet with ill-tested and ill-thought out enhancements to a once great product. I really think that I might have to make the switch back to OneNote (shudder) Not happy.
