When using MediaWiki on desktop, it is possible to reach the page history from diff view by clicking the "View history" tab (example).
On mobile, there is no way to reach the page history (example).
With the page title no longer leading to the current version of a page (T200804) even more clicks are required to eventually reach the page history. For experienced users, it's usually faster to manually edit the URL.
This unnecessarily complicates the workflow for editors tracing changes (especially on highly frequented talk pages such as the village pump).
