"Edit doesn't save I open my doc I edit then click the save icon it flashes a saved message immediately restoring the doc prior to editing  I find the saved edit (which was not easy!) It was all wrong it saved a exact copy of the un-edited doc except it had a half a paragraph cut and pasted to the end of the last paragraph on the doc. That is all kinds of retarded!"

"No native calendar and contact sync (saying someone would need a 3rd party app for that is like saying you need to install Internet Explorer for HTTPS support in Google Chrome...) Yubikey U2F doesn't seem to be working with this app  but it does in my Chrome browser (No U2F support #796)."
