Issue 1, this is what I'm seeing (text descriptions will have to do as I don't know how to take screenshots)
Start G+ app
Go to all Circles
Menu button > Send Feedback
Browser opens up with "Google+ Help" page:
"Thank you for your interest. If you would like to contact us, you will need to do so in one of the languages below. We are unable to provide email support in your language at this time"
Big long list of languages, I click on English (US)
Loads up Share Google+ Feedback
Select Satisfaction level (Slightly Satisfied in this case)
Select feedback option
The only thing left on this page is "Submit" which I click
Browser loads up page saying "Thank you for helping us improve Google+" There is nothing else on this page
Go to "All Circles" and find a post with an image attached (A Google one about the new app update) The image in the stream is wide and short
Click on post (same image in post as in stream which is low res BTW)
Click on image in post
Image is the same resolution but is square (not distorted cropped). The image in question is a screenshot of the new app so it should be portrait aspect
If I click download and go to my Gallery App, the image appears in full.
I get the same problem with images if I go into Photos and select any album image. FWIW, I'm looking at one right now and the "cover image" of the album is wide and short portrait and is the full-width (but not height) of the image. When I click onto the image, I get a square version that is full height, but not full width.
