This happened to me one other time when I upgraded my iPhone to a newer model. I briefly was unable to see my notes though it recovered on its own when I logged out and back in. (I only use one email for this app since I also access it with my work computer, my personal iPad and MacBook.) This time I am experiencing the same problem but this time unable to get my notes. I have 10 years worth of data stored in the app and it appears they've all gone. I've entered a couple of tickets but seeing some of you enter much more than me, I'm thinking it will be a while for support to answer my plea. Thanks.
