Deep links allow you to open a tab when the page loads.
You can enable or disable deep links from the Settings > General page in the app.
When the Enable deep links setting is checked, a tab ID is added to the end of the URL each time a tab is opened, like this:
If a URL containing a tab ID is sent as a link, the tab with the matching ID is opened when the page loads.
Deep links do not scroll the page
Deep links simply open the tab, they do not scroll the page to that tab.
When the Enable deep links setting is unchecked, tab IDs are not added to the URL and tabs can not be linked to directly.
