Can you save a sort using date created field?

The company I work for uses an app called "iView" to sort and review images for editorial purposes. This program was "end of life'd" quite some time ago and It's time to finally move away from our old program.  A traditional DAM software, isn’t an option so we're going to use Bridge instead for our editorial and production needs. It seems like its going to work except for one part....

Saved sorting that can be viewed amongst different users. As of right now, changing file names is out of the question. We tend to re-use assets across different projects, so having to change the file name would break links on existing projects OR create many many duplicates of the same image.

This is a short example of our current process: User1 (the editor) sets the order using meta data fields, in which the images should be placed in the working document. User2 (the designer) needs to open those images to see the same order that User1 set them in. In the old application, we are able to sort images by the "event" field in the IPTC Core metadata field, but this is not a sort option in Bridge.

My instant solution for this was to use the “date created” IPTC Core metadata field. This seems like it would work, because it is a sort option, and its a field that can be edited in the metadata. Not to mention that we create dated products, and our current process is to sort using dates so it wouldn’t be a far stretch out of our current workspace. Example:

Image1 date created: 01/01/19

Image2 date created: 01/02/19

Image3 date created 01/03/19

TWO EXCEPTIONS

1. I can’t seem to get the dates “to stick” on some images while I’m testing this new process. I can see the date change in the IPTC core field, I am saving the data. But it doesn’t change in the date created field in the properties window. And only on some images. Other images it works
2. When I do change the date created field. And I go to “sort by date created” …. The images do not list in the correct order! It still appears to be random! I wish I could show an example here. But when I sort with this field, the first images to appear are 1/14/21, 1/8/21, 1/16/21 ... totally random. I’m even applying the dates as 01/08/21 …. But adobe seems to be auto adjusting these to not show a 0 in front of a single digit number.

SO, is this the entirely wrong way to go about this? Is it possible the images where the date created isn't changing to be locked in some way? 

Is changing the date created field a recipe for disaster? Is there a work around?

Should we be using a keyword to set each date? There are a few downsides to this, we cannot have a collection of 30 images and see them as a whole in day order and it would be a lot of keywords to have to constantly maintain.

I know Bridge isn’t intended to be used across multi users like this…. But we have to make this work for now, so any insight would be appreciated!
