Hi, @Amy Bentley
First, open a single photo in the Microsoft Photos app. The Designer button should appear in the title bar when viewing one photo.
Also try updating Photos:
- Open Microsoft Store.
- Go to "Library."
- Select "Check for updates" and install any update for Microsoft Photos.
- Restart Photos and check again.
If it is still missing, go to Settings > Apps > Installed apps > Microsoft Photos > Advanced options, then select "Repair."
To help narrow this down:
- Are you using Windows 10 or Windows 11?
- Is the Designer button missing for every photo you open?
- Are you signed into the Photos app with your Microsoft account and connected to the internet?
Click "Add comment" to let me know.
Thanks!
