I've edited a photo/video, but Prequel cannot save it. Why?

This issue may happen if Prequel doesn't have access to your files. Please make sure that you've allowed Prequel to access your photos.

To do that, please:

Step 1

Go to Settings > Apps.

Step 2

Find Prequel and go to Permissions > Storage.

Step 3

Make sure that Storage is on and has access to All Photos.
