PWA using Ionic 2

We are working on revamping our mobile site to PWA using Ionic2. We completed one module and while doing the integration testing we found that the ion- tags are not supported in UC browser. But some good number of customers are visiting our mobile site using uc browsers. So is there any way to handle uc browsers using ionic 2 apart from using the general - div - tag based approach.

Also one more issue we are facing while using routers - by default its adding # to the URL which is not SEO friendly. Requesting your help to overcome this issue as well.

Thanks in advance!!
