All the pictures I've edited on my Mac show in the Photomator albums on my devices and at iCloud. com. I just cropped an image ini Pad Photomator, and it shows in the Photomator album in my phone and also in the Photomator album at iCloud.com. I'm not sure about the Mac-- it's busy right now.
Could you tell us a bit more?
- Do you see your edited pictures at iCloud.com?
- Do you have “Optimize Storage” checked in Photos’ Settings
- Do your pictures synchronize otherwise?
- Do you have more than 10% free storage on your iCloud account?
- What is your storage on this iPad? At Settings>General>iPad Storage, my iPad says 209.5GB of 512 GB used. What does yours say? Do you have more than 10% free storage on your iPhone?
- What is your storage on this Mac? At System Settings>General>iStorage, what does yours say? Do you have more than 10% free storage on your Mac?
You can try these things:
- Restart the computer (of course)
- Re-start in Safe Mode. This bypasses certain potentially disruptive processes, and it often helps. Safe Mode is different for different computers, so see this:
Start up your Mac in safe mode - Apple Support
- Force restart of the iPad
Force Re-start iPad
This is different from a simple Power Off. For me, the logo appears way after the Power Off notice.
Let us know what you find…
