The iOS app allows you to upload media directly from your camera roll, iCloud Drive or any other third-party storage providers you have connected (like Dropbox and Google Drive) into a project. To do this, select the three dots on the top right hand side of your project, tap "Upload" and then choose an upload method.
You can upload multiple files at a time by selecting them and then choosing "Done" on the top right.
Here is an example of what this workflow looks like:
- Uploading files on the iOS app
- Downloading clips for offline viewing on the iOS app
- Commenting on clips with the iOS app (doesn't exist yet)
