It's about time!
Google is revamping your experience on the iPad! It is about time as Google Drive is seriously lacking compared to Drive on other devices. The app is actually moving to operate less like it does on a computer or Android device and more iOS like.
Google Drive is being split into 3 different apps. I would guess the Drive app will cease to exist once the changes are complete. Google Docs and Google Sheets is available now and I suggest you upgrade right away. Google Slides will be coming soon. This will be particularly nice since you currently do not have editing ability on Google Drive. You can only view Google Slides. Click on the links below to download from the Apps Store!
Google Sheets will allow for offline editing, sharing with others, sheet creation and more.
Google Docs is similar to Google Sheets as it too will allow for offline editing, sharing with others, document creation and more.
Both apps have added functionality and are a significant improvement over the Drive App. These apps can be accessed using your own personal Gmail account or even better your MyTools2Go Account.
