Wanted to provide an update here.
First of all, if you are running into bugs (like all your photos have the same date) please reach out to support. If you’re on mobile, you can shake your device, if you’re on the web, you can use the settings cog.
As for the ability to change metadata on photos, that’s not something we currently have on the immediate roadmap.JB commented
Some of my pictures in photo gallery have come out dated 2025 !! Why, I certainly didn't date them as such, I see some other people are having this same problem, would appreciate any help to rectify this.
