Can you access Google Drive from the Files app? If you can, I don't see why you can't save to Google Drive when printing to PDF. It works for me at least.

Yes I can access Google Drive.  I've tested with two accounts.  It worked before and might have broken after the 50 update.

When you get to the "Save As" dialog:

1) What do you see in the left pane?

For me, I see:

Google Drive
  - My Drive
Downloads

2) Assuming you see "My Drive" - can you select it?

For me, the answer is yes.

3) Assuming you can select it, if you hit the "Save" button, what happens next?

For me, I successfully saved to Google Drive.

Testeed with Chrome 51 beta channel here. I can find another Chromebook and test with Chrome 50.

I can "save" to Drive but not "print" to it.  Normally after clicking print and then selecting "save as PDF" and click save, I believe you could save to Drive.

If you can't, could I request that you could?

re: comment 4 - in comment 3, I tried to explain to you what's happening for me when I print -> save as pdf -> get the save as dialog. You repeatedly said this does not work for you, but I don't understand what's going wrong for you. If you can better describe what you see, or attach some screenshots, that would be helpful.

Thanks. The screenshots are helpful. I'm not sure why only "Downloads" appear when you are saving to PDF. I'll go find another Chromebook to test with.

I tried a falco device running Chrome 50 like yours and it behaves just like your device. However, my other device with Chrome 51 works fine, so I'm guessing it could be that your bug was recently fixed in another bug, and all you have to do is wait for your device to update to Chrome 51 in a few weeks.

This seems to have been fixed by  Issue #595503 

re: comment 10 - thanks, I knew there was a duplicate bug somewhere. Looks like Chrome 50.0.2661.104 will have the update, so any day now rather than in a few weeks.

I'm now on  50.0.2661.103 and it's still broken.

You need 50.0.2661.104. It should roll out shortly.

Ah cool.  I thought you had a typo.
