We are currently experiencing an issue on Apple devices with iOS 13+, which is causing images in the newsfeed and across the native app to appear blurry. The issue only affects the image preview - when the user enlarges an image it appears in the expected resolution.
We have identified the cause and our developers are preparing a fix. This fix will go live with the release of our app version 4.1. More details regarding the release will go out via email soon.
Rest assured, we are taking this issue very seriously and apologize for any inconvenience it has caused you and your users.
Feel free to reach out to us via firstname.lastname@example.org
if you need any assistance or help.
