Missing photos from upload

Question

In December, I noticed that Dropbox did not back up random sets of photos from my phone using the Camera Uploads function in the app. For example, Dec 13 I took over 43 photos and it didnt back up any of them.
Dec 19 - all 10 are missing.
Dec 18 - took 46 and only 4 uploaded.
I’ve run the upload dozens of times since then and it is still not updated.

Since then I have contacted c customer support, and they have been very responsive, but have not given me a solution. I’ve checked all the boxes for the questions that they asked and it doesn’t appear to be a problem on my end that they can determine.
So I guess my question is, has anyone else experienced this issue and what did you do to resolve it?
Also, how do I trust that this hasn’t happened before without going through all of my photos individually?
Thank you

Thanks for the info, if the support team have done all they can to assist, then there would be little I can add here for further troubleshooting on our end.

To ensure that those photos are on your account now, I'd recommend uploading them manually in the Dropbox mobile app.

Good morning,
None of the missing photos are live. The majority are jpegs with a few videos.

Hi @MrsP208, thanks for bringing this to our attention.

Are you able to upload those missing images manually via the Dropbox mobile app into your account?

Are any of these photos Live Photos if you're using an iOS device?

This will help me to assist further!
