Working Offline message is in error

I have been using Kami for along time and suddenly it says “working offline” and I am not. Then it won’t let me proceed in my document. It’s 20 pages but when I try and go from page 5 to page 9 for example it kicks me back to page 5 and I can’t edit. Using Chrome OS chromebook pixel. I uninstalled the extension and the application. I closed and open that document plus another pdf but still a problem. Ideas? Edit - rebooting laptop seemed to fix the glitch.
