Hello all, I am have an issue in Safari both for iOS and MacOS where when uploading a file with XMLHttpRequest() progress is not sent in a nice even interval that allows for a smooth upload progress, it is set randomly at large intervals. This means you do not get a smooth nice progress but rather large jumps because the amount of data sent is in large intervals. can see data being constantly sent from the device and at the server level so I know the upload is working.
You can see the problem here: https://imgur.com/a/Qhh3Q8u
I am pretty sure this has to do with the server config and something that is unique to Safari, I am running Nginx 1.27.0 and Php 8.2. This problem does not happen in Chrome or Firefox on my desktop, in those browsers I get a smooth progress and data sent amount. If you have a fast connection you do not notice this problem, slow connections and it's very apparent.
Has anyone figured out what is needed to get this to work properly?
