Default [Q] Google Drive - Not Enough Memory Error

My friend just made the transfer to android (from an iphone) and had the unfortunate event of getting a message I've never seen before. When he tries to save a docuemnt in the Google Drive App he gets an error: "Not enough memory"

It's a new phone and I'm not sure if the error is from the app or the phone. Obviously it works on mine just fine.

I haven't been able to find anything searching online. Does anyone have any idea what this is from or how to fix it?

We tried the obvious uninstalling/re-installing and clear the cache/data, but to no avail.

Thanks in advance,
