If you are unable to edit your PebblePad workbook (e.g. you are unable to type into any of the text boxes), then you are accessing your workbook incorrectly.
To open the editable version of your workbook, please ensure that you do this by opening the asset store from your PebblePad dashboard.
Alternatively, you may want to save a regularly used workbook/asset as a FAVOURITE. To do this, follow the instructions in the area named 'favourites' on your dashboard. You can then easily access these assets from the dashboard when you need them.
Please Note: If you try to access your workbook via ATLAS (the blue circle icon), then this will give you a READ ONLY view of your workbook.
