After upgrading to 9.x, when in the dashboard and selecting the drop down list to choose a site, it only shows 9 websites. You have to click Websites to see them which takes longer to load.
Is this a bug or by design?
You should see the search field in the website selector and search for other websites
Is there any way to get the full list?
With over 100+ websites, remembering all the names is not easy.
you don’t need the exact name, just parts of it.
With over 100 sites loaded on each request its simply slow.
but if you really want, you can change the setting site_selector_max_sites in your Piwik config file, and set it to 200 or some big value.
