I just installed Google Drive (GD) on an LGE Nexus 4 and uploaded a spreadsheet to a directory there. There has been much hoopla! in the news these past few days about the ability to edit spreadsheets on GD using the newly-released Android app. Using the app, I can access the spreadsheet and open it. I can select any desired cell, but am unable to edit the contents even though the cells of interest are unlocked in the original sheet before uploading. From aPC I allowed conversion to whatever format Google Docs needs, but am still unable to make changes to the sheet on the Android device. Has anyone been successful editing spreadsheets on Google Drive?
