If you are having issues uploading or loading the content and the error message displayed doesn't indicate how to solve the issue, please try the following:
- Close the app from your background processes and launch it again. Here's Apple's guide on the topic.
- Update iOS and Slideshow to the most recent version.
- Verify the format of the content you’re trying to import. All pictures and videos in your camera roll and recorded with your device should be compatible with the app. Pictures or videos added to your Photos via other means (for example, those received via WhatsApp or Airdrop) and those edited with other apps (for example, a different video editor) may not be recognized by the app.
- Check that all assets in the project are saved to your phone's storage. Assets saved to Cloud sources such as Google Drive and Dropbox won't work with the app. If any of the project's assets are saved on the Cloud, try downloading them to your phone and re-adding them to your project.
In case our suggestions didn’t resolve the issue, you are welcome to send us a screenshot or a screen recording that could show what you experience.
