I try to get my office 365 installation on my Android 10 (Huawei) Smartphone to modify excel files that are stored on dropbox.

But the files are allways read-only. Even if I create a new one on the android smartphone, they are read only after saving.

I can't find something about this via google, thats why I think it is some minorr issue.


According to my research, editing is available for the following file types on Android: .docx .xlsx .pptx Any other Office files will be read-only. So please check the Excel file types, if they are not .xlsx, try to modify it.
