I'm trying to a make an element that uploads an image to the server. I'm using this component : https://www.webcomponents.org/element/bluewatertracks/bwt-uploader
The Problem is that if I use the above element with polymer 1.0, then its works like a charm but if I use it with Polymer 2.0 then some of its features like progress-bar and delete button don't work.
which one should I choose?
Can anyone please help me out?
