with the Android- and iOS-App and with https://tweetdeck.twitter.com I see some images, which are trimmed to 16:9. It’s a bit weird, cause these images have a perfect 2:1-size, so the official and correct aspect ratio for image previews in the timeline.
Is this just a test, a bug or a general change?
Furthermore the most appearing images have the “old” ratio in 2:1. So I’m a bit confused, why new 16:9-versions show up.
