Steps to reproduce

Hello,
Tested on multiple iOS devices + multiple Uppy configurations as well on the example page - https://uppy.io/examples/
The issue is when selecting around 50+ images, and then clicking "Add", there is a delay of around 10-20 seconds depends on the device, while all android phones tested works just fine immediately.

Steps to reproduce -

1. Enter https://uppy.io/examples/
2. on an iOS device, click "My Files", select 50+ images from the gallery (local files)
3. Click "Add"
4. Notice the huge delay until the photos appear on the Dashboard UI.

Expected behavior

Photos should be added immediately after clicking "Add"

Actual behavior

Huge delay, around 10-20 seconds and even more on older iPhones.

Hi, I don't think there is anything we can do here. To access files you use a browser API, we don't implement that API ourselves. Over time I've seen quite some iOS specific bugs that were resolved over time.

We could double check with other file plugin libraries to see if it's faster or the same.

@Murderlon Thanks for the reply!
I see what you're saying and that makes sense. Although I tried as a test to upload the same files to Google Drive and it was immediate in the same iOS devices.
If it's possible to double check it'd be awesome, thanks a lot in advance

Just tested this on https://pqina.nl/filepond/ and it happens there too for me on iOS Safari.
