I'm using Chrome 61.0.3163.100 on my Mac running MacOS 10.12.6. When I try to get a file restored from iDrive running on my iPhone (in this case it was a Word document), I bring up the Sharing Sheet and send it to my Mac via AirDrop. When my Mac receives it, it is a URL that opens in my default browser (Chrome); but that just displays a web page that says:
---
This XML file does not appear to have any style information associated with it. The document tree is shown below.
<tree message="ERROR" desc="INVALID PARAMETERS"/>
---
If I copy and paste the *exact same URL* to Firefox, it works properly... so there's something about Chrome/Mac and what it is looking for that is not being provided by iDrive.
