I encountered the following problem and would need some help:
When I share a folder with one/multiple persons, they can access it. Let's suppoe I gave the persons managers rights. So now they should be able to create files and edit files. Actually they CAN create files and also edit and save THESE files (that they created themselves). But as is seems, it's not possible to edit and save a file someone else created. Thats odd for me, as I thought all files would be shared, and the managers and admins can edit any file in the folder...

Am I doing something wrong or is this a bug? I know that the spreadsheet and "word-file"-editor are beta.
