Hey sarah.67.sc

Thanks for the question. I understand you are experiencing issues with Photo Stream. The following resource may provide a solution:

Also, remember that new photos will be uploaded to Photo Stream when a few requirements are met. Photos taken prior to turning Photo Stream on will not be uploaded.

When do photos upload to My Photo Stream?

 

When you enable My Photo Stream on your devices, all new photos you take or import to those devices will be automatically added to your photo stream.

 

iOS devices: New photos you take are automatically uploaded to your photo stream when you leave the Camera app and are connected to Wi-Fi. My Photo Stream does not push photos over cellular connections.
