Can I sync Apple Numbers spreadsheets via my WD Mycloud. I have all of my spreadsheets in a folder in WD sync but they do not sync, is this because they are also synced with iCloud ?

Hello,

I don’t think it’s because they are being synced with a different app.

I haven’t heard of any specific issues with these files.

Make sure that they are not open.
