Vw link problem

Trying to migrate my app to V2. Following just does not work (no linking):

<div class="toolbar tabbar-labels toolbar-bottom-md no-hairline no-shadow">
    <div class="toolbar-inner">
      <a href="index.html" class="link ">
        <i class="icon icon-river"></i>
        <span class="tabbar-label">Journeys</span>
      </a>

Grateful for some guidance
thanks

Adding external makes it work:
<a href="index.html" class="link external">
solved the problem but seems illogical…

V2 requires all your routes to be specified in app parameters check routes documentation

Interesting…
I haven’t used any routes and it all seems to work fine after upgrading to V2.
cheers
