Facebook App Low Image Resolution?

[bladerealm124]

I noticed recently when viewing images on the Facebook app they are super low resolution (720x479). I previously would upload images directly to Instagram from Facebook but I now find them far too low res to do so. When did Facebook implement this change to the app and is there any way to reverse it or use an older version? Images viewed on the Facebook mobile and desktop sites are full resolution (2048px width) but all images on the app are now shown at a lower resolution. This is with a Verizon Galaxy Note 4 and the same appeared true on my girlfriends T-Mobile Note 4.
