NOTE: I looked for a duplicate but couldn't find an open issue.
If URLs with multiple domains are tracked to a single site, for example
/some/path in the Transitions UI should show data for both piwik1.net & piwik2.net URLs.
Instead, only data for one URL is used. The URL that is chosen is the URL that ends up as the
url metadata in the
Actions.getPageUrls report. The action matching code in
TableLogAction::getIdActionFromSegment doesn't ignore the host so only some data is selected.
Some possible solutions:
/some/path. The pageviews count in the dropdown will be correct, the pageviews count in the main visualization will be incorrect.
NOTE: This bug is visible in our Transitions UI tests.
From our UI test:
