Changed timestamps are discarded in shared iCloud albums

Hi there,

I’m using iCloud Photos for my photo library. On vacations, I usually take photos during the day, and add some explaining screenshots in the evening to my library. Since I want the screenshots to appear next to the actual objects in my library, I adjust the timestamp of the corresponding screenshot to roughly match the timestamp of the photo of the described object. Example: a took a photo of a building at 1 pm, and added a screenshot describing the building at 9pm. Afterward, I adjusted the timestamp if the screenshot to 1:02 pm so that they are displayed next to each other.

If I now select these photos and share them via a shared iCloud album via the public iCloud link option, the screenshots have their original timestamp. Thus, they appear at a different order than the original photo. In the example, the screenshot of the building was displayed at the end of the shared online album instead of next to the photo of the building.

The behavior is the same if I simply select the photos, and let the photo app generate a 30-day temporary iCloud link.

Is this intentional? Or is this a bug? Or is there a way to avoid this problem?

thank you in advance!
