    We have the same problem here. Haven't been like this earlier, it's a problem we got now.

    Microsoft need to supply us with a solution.

    The workaround right now is to open the in web reader, add something to a cell, get a cup of coffe and then open it in the APP.

    Members of my Team are also experiencing this problem though, as the Team owner, I'm not, leading me to think it's permissions issue.
