Uploading Multiple Media Attachments in Twitterrific (iOS and macOS)
We're really excited to be offering the ability to upload multiple media attachments in tweets! However, there are some limitations to this feature that you should know about:
A single tweet can either have no media, or 1, 2, 3, or 4 photos, or 1 animated GIF, or 1 video. This means you cannot do things like attach one photo along with a video.
