Evernote has worked fine for me on iPhone 5s and iPhone 6. Until now. I start up the app, and it appears to be syncing, but I can't do anything -- tap on a note or change settings or anything -- except double click the home button, quit the app, and restart only to find that it appears to be syncing and is unresponsive. I tried using Wi-Fi, I tried using cellular data, I tried waiting for several minutes -- nothing makes a difference. I saw a discussion on this forum from about 10 days ago but without any solutions. The app just started working again, at least for some people. https://discussion.evernote.com/topic/78569-ios-sync-bug/ That doesn't really seem like a tolerable solution for a business-oriented productivity app. So what do I do to fix this? Is it a problem with the app? Is it a problem with Evernote's servers?
