Drag and Drop file upload not able to upload more than one file on mobile phone browser

User is able to upload more than 1 files using this Widget on a desktop browswer, however on mobile phone (i have tried iOS), user is only able to upload 1 file only. Any way to overcome this issues?

Unfortunately, Drag and Drop File Upload tool doesn't work the same way on the Mobile platform the way it works on the computer. Hence you cannot upload multiple files on mobile.

If you need your users to upload multiple files on mobile then you can use the normal File Upload field to your form. 

I hope this helps.
