Multiple uploading of photos will not attach when using phone browser

Also, the last page of the form involves multiple photos being uploaded. Lots of times the mechanics are noting that they'll upload a photo but it won't actually attach. I've experienced this myself when using it on my own phone. The progress bar will fill, but then nothing will show up. Furthermore, after they've uploaded all their photos and click submit, there'll be an error on the form telling them that a mandatory photo is missing. When they go check the item, the photo is there and there's no way to make the form recognize it without going back a page and submitting from there. In those cases though, sometimes it ends up just deleting all the photos when submitted from the earlier page.

I have checked your form and it seems you are using an Image compressor widget.

However, this widget seems to be depreciated already. Can you try using other upload files widgets? or use the upload element instead?

Let us know how it goes.

Thank you.
