Cannot use "Attach File" in form using Safari IOS


I cannot use the attach file button on a web form using Safari in IOS.
It works fine in Safari OS X , opening the little panel for selecting the attahment type.
BUT…in IOS using Ipad or iPhone lastest version 12.2 ( XS and iPad pro ) clicking on it used to open a new window for taking picture or uploading. Now it does nothing …

HELP. I need to upload some pics in the form.
