It's the new Android picker. It has to be this way or the app does get approved on the Play store.

So the Play Store won't let Amethyst access other folders, but still allows other apps to? What's that about?
Apps can be updated if they don't use the new picker or a permission system that is per file, and not for the entire folder like before. It is a good move, but the picker sucks.
And a seperate question: is this supposed to happen when replying to people with gifs?
Whaaaa.. no that is not supposed to happen. Which version of Android are you on?
Ohh this is when you share from the Files app? Humm..
No. If I send a gif using the Samsung keyboard, it opens a new window to upload. I have to copy and paste the link in the original window. I had 4 seperate Amethyst apps open because I kept trying in the new windows 😆
Ohh yeah, that's a Samsung thing. I am not sure how to fix that. Hopefully it will be fixed from upstream when they start using the new text field with gif support.
