Great Productivity Tool!

I do quite a bit of writing using LibreOffice, which doesn’t have an iOS/iPadOS version, and this is a fantastic tool to continue my work on my iPad when I’m away from my Mac. Only issue keeping me from giving it five stars is the lack of touchpad scrolling support. Not being able to scroll using my iPad keyboard’s touchpad is a pretty big annoyance. If that was fixed, I’d up my review to five stars easily!

Disappointed with update

It seems that we lost the page setup in calc. Ant orientate spreed sheet from portrait
to llandsape.

Lost all my work due to “disconnected from server” error

Got a “Disconnected from server” error, which froze the editor, never went away, and caused me to lose hours of work. Why is this program connecting to a server? Why doesn’t it let you save your work while it’s doing this? Why does it force-lock the app while it’s reconnecting? Everything about this is an infuriating waste of time.

App broken: Constant crashes & loss of work.

I don’t know what happened with the last update, but the app is now entirely broken and unusable. It crashes often, throwing up a pop-up that says “Reconnecting” despite it being an offline app. The pop-up gets stuck as it never actually reconnects to whatever it’s trying to connect to. Whatever work I was working on is lost. The crashes are constant and unavoidable.

Sheets….

First couldn’t figure out why I half the buttons didn’t work. Have to be in edit mode. Then when I would try to access the sheet settings menu by long pressing the sheet, it would immediately select duplicate. Occasionally you can slide your thumb around and then let go. But not always. attempting to delete them, I had about 16 duplicates before I finally quit. Three stars cause the other stuff probably works.
