Uploaded PNGs not working on iOS



Hi there,

We are uploading PNGs with the REST API, and they are working fine on web and Android, but in the iOS app they show up as blank grey squares.

Here is a tweet that is having this issue: https://twitter.com/jenkellyjen/status/650961713177587713

Here are the screenshots of how it looks on web,ios, and Android. (I can only upload 2 images, but it works on Android.)

Edit: It also works fine on iOS from mobile web.
