What do I do about my Live Photos and metadata on other uploads?

Thank you for the reply so soon, Jay ! 
I am very scared now that you said anything uploaded via the plus button resets the creation date. I have uploaded so much that way. I guess I just have to live with my files this way. 

This makes me really want to know now if there is a way to upload to Dropbox without any changes occurring?

For example, should I go on mobile Safari and to dropbox.com to upload my images?

I cannot use the automatic camera uploads feature because I am only saving some pictures and videos; not everything is mine.
I did notice a "Mobile Uploads" folder was created: what happened to those creation dates? Changed, too? 

The iOS application in the past used to allow me to see the metadata on my files and media; it does not any longer for most file types or media types. I could have seen this altering of information embedded in my storage happening if the opportunity to view that stuff existed as easily as it once did. There is no information button on most items.

Why is the plus sign front and center if it changes your uploads?

I thought Dropbox was for backup...

Would this round about way through Readdle Documents work?

If I zip up a folder with Live Photos in it, will that preserve the Live part once I download and unzip somewhere else (like, a friend's desktop for example)?

How about creation dates and other metadata on any kind of file or photo if zipped up before uploading to DB?

(Just trying to think of some way to save them. I don't have much time to remove my stuff from my mother's iPhone I'd been borrowing often. She wants the space back. Also, I am imagining ahead to audio recordings.)

So, thank you very, very much for the quick simple "no" regarding Live Photos!

Thank you as well for the tip about uploads from the plus button!

If I am understanding correctly, I am going to have to get creative and just except that when I finally have a laptop of my own, and download all of my Dropbox (like a hard drive) onto it, the iPhotos thing will be way, way wrong. Unfortunately I used that and cannot reupload those original items. I thought they were safe and erased what i had transferred to DB already; wish i had asked sooner! For all other items going forward, I will just have to have an extensive folder system like on my old PCs before metadata and all that did the organizing and relevant things for me: folder name > folder name year > folder name year and month > folder name year and month and day. 

Thanks again for the help so far,
