I've set my iOS camera uploads to add only new photos, but it's trying to re-upload everything.

Thanks for the additional info, jlo-nyc.

It might have to do with the fact that even though the photos are old, this is a new phone, so it needs to scan them.

Have you tried to delete the Dropbox app, restart the device and then reinstall it, to see if it helps?

I haven't tried that, but when I had to factory reset the new phone, because something was causing other issues, I had to download most apps as new, so this current app was technically a new download and install. Does that make sense?

It does make sense, jlo-nyc.

Can you open the Dropbox app, tap on "account" and then on the gear icon, to find the version of the app that you're using, please?

It's App version 406.2.2

Thanks for the clarification jlo-nyc 

Could you also send us a screenshot of the screen you get stuck on so that we can have a visual too? 

Can you see this?

This is where it ultimately got stuck though 

seems the files are too large for upload here, how can I do this?

Are you getting any particular error when trying to upload your screenshot here jlo-nyc? 

Yes - it said the files were too large. 

In that case, you can try grabbing a new, smaller screenshot or use a shared link instead jlo-nyc

Hi from me too, jlo-nyc! Thanks for these screenshots. Can you send me one more visual of what you see when opening the camera upload settings on your iOS device (including the albums from which your camera uploads feature is currently uploading images)?

Dropbox uploads from my iPhone's Photos app, from the main library, no specific folder.  I uploaded the screenshot of my camera upload settings from my Dropbox app to this folder (I assume that's what you were asking for): 

Hey jlo-nyc!

After reviewing our entire thread, I believe the best course of action would be for you to set camera uploads to backup "new photos only". Then, you can manually upload any older photos that aren't already online.

Keep in mind that if the "All my photos" option uploads everything from scratch -which seems possible in this case- there may not be a way to prevent it. 

You also mentioned having some duplicate content, right? If I misunderstood, feel free to clarify. However, if duplicates are an issue, please check the file names and sizes of the files and compare them to confirm they're identical. 

Thanks - When I select "new photos only" it sets a start date to today (which I cannot control), so I assumed it's not looking for new photos based on sync, it's date based. I don't remember it being like that in the past, but that makes me think it will only start looking for new photos taken on or after that date. Is that not correct? Will it upload new photos I took since the last upload? That's why I had selected "All photos" in the Back up setting.

I don't know that there are actually duplicate content issues, I just wasn't clear on why Dropbox was scanning EVERYTHING rather than only grabbing what was new.

Hey jlo-nyc!

I tested this on my end, and it is indeed date based.

if you select "new photos only" today, then it should upload content from your camera roll starting today, or from the moment you enabled the feature.

Thanks for testing that. So this is the issue for me, I don't do this back up daily, so this is not helpful. This is why I had it set to "All my photos" but it seems to scan EVERYTHING.  I'm pretty sure it did not used to do this, thus the questions and why I'm so baffled by how this works. Perhaps I'm wrong and it was always like this, but I'm quite certain it was not scanning thousands of photos for possible uploading when I had the app on my iPhone 11. So... I guess I'm at a loss, and probably should just keep it set at "All my photos" and just know that it will take a while before it determines what needs to be uploaded.
