Bests & Worsts Reviews from Amazon

So, as of right now apparently the kindle FB app is "21 months out of date". Unlike the up-to-date version available EVERYWHERE ELSE, post "reactions" (the heart, laughing, wow, sad, angry, etc.) and other features are unavailable (which is a little annoying) but by far the the worst part of this outdated app is how easily it crashes. If I'm scrolling through my newsfeed and scroll past a video (even if I don't try to watch it and scroll really quickly) the app freezes, then crashes. If I try to watch a video on my newsfeed, the app crashes. I tap a photo/pic for a closer look, the app crashes. If I tap a link on my newsfeed or saved links, the app crashes. Looking at other reviews I'm clearly not the only one annoyed with the lack of updates. I think it's absolutely ridiculous that, despite multiple complaints/unfavorable reviews (mine now included), nothing has been done to update/fix the app in "21 months" when that same app is updated regularly on the Apple devices and Google Play. Not cool.
