Problems with xlxs files not being opened

[chrisdur]

Hi,

I'm wondering if anyone else have the issue with xlxs files not being able to open them (specially downloaded on the desktop).

The message says its unsafe and I need to open them from the security and privacy center but thats not a good option.

This only applies to xlxs file no other Office365 files.

I've tried to uninstall xlxs and re-install it but still the same issue, it says it don't have/ recognise the extension...

ANy tips are more then welcome!
