Yes this is happening to me to. Happens only on my IOS devices. I used to prefer using the IOS app over the desktop. But for me, now the desktop app is much faster. Every keystroke is a 5-10 second delay. My IOS devices are new IPad Air2 and iPhone 7. My iMac is 6-7years old and English the EN app runs faster. I've been using Evernote for 8 years and this is causing to consider switching. OneNote is interesting to me. Help us EN!
