iCloud Photo optimization not working

Alan,

Thanks for checking that. Based on the article about using iCloud Photos, Set up and use iCloud Photos, you can expect your photo library to be optimized only when you need space. The optimization starts with the photos and videos you access least. In Settings > General > iPhone Storage, is your storage space low or do you have space available?

Thank you.

Hello Alan Musgrave, 

We understand that you’re seeing the space the Photos app is using on your iPhone increase more than expected. 

Let’s check to see if that optimization may still be in progress. From the Photos app, tap the Library tab > All Photos and then scroll down a bit. You’ll see the number of photos and videos you have come up and below that will be a status. It might say an upload is in progress, it might say things updated recently. What does it say? 

Thanks.
