I have many Iphone 10 photos with missing correct exif creation date. For example this photo was taken on 2020:7:29 (Looking in my agenda, it was an import event).
What am I doing wrong? I'd like to organize my photos in <year><month><day> folders and this leads me to issues.

I'm starting the think it might has to do something with dropbox. I have been uploading some of my photos automatically to dropbox.
Looks like i use .heic originally and when uploading to dropbox it gets to .jpg and removing some exif data :(
All I can say is that this definitely isn't an original iPhone JPG image.

That seems to be a very strange for Dropbox to be changing the format of the image, but it looks like it's an option. See here (https://help.dropbox.com/installs-integrations/mobile/ios-formats).
Have you checked to see if the originals are still on the phone?
Otherwise, there isn't any time data in the file to fix it with and the filename isn't a timestamp.
After testing with one photo with dropbox camera upload (iphone X to dropbox) it does not indicate it's changing the EXIF data. Thats the good news. Have to look further what has gone wrong in my setup..
