I have a problem with a spreadsheet that is located on OneDrive. It's read-only on my phone.
It started after I updated my phone from 7.5 to 7.8. If I create a new document on my phone, I can edit it without any problems, but when I edit it from OneDrive, it becomes read-only on my phone.
I have searched through the OneDrive options but I couldn't find a solution. Has somebody encountered have this problem before? How can I fix it?
