Here's the summarised changelog (for v22.214.171.1240) since the last time we featured this app:
- Under the hood improvements
- Windows Hello fixes
- Ad scaling fixes
- Support for (and improvements to) 'Right to Left' languages (e.g. Arabic)
- Improved Italian translations
So yes, nothing drastically new, but like many things in the Windows 10 Mobile world it still works just fine, no matter what scare stories you hear about the OS from some parts. We may have lost (or are losing) some native applications, but this is third party and there's no reason it shouldn't carry on getting updated for a year or two yet.
You can grab GDrive.NET in the Store here. It's free to download and try, with ads that can be removed with an in-app purchase, along with unlocking some premium features. It's what I did. See also my full review of this essential Windows 10 Mobile UWP app here.
