When viewing a diff on mobile (example) there is no link to the current version of that page.
Previously, clicking on the page title led to the current version. Since a couple of days, clicking on the page title leads to the old version of the page associated with the diff.
When checking talk pages on mobile, I often use my watchlist, the page history, and diffs to follow a specific conversation. Previously, I could join the conversation by clicking the page title and editing the relevant section. Now, I need to first click the page title and then find the link to the current version in this not-quite-mobile-friendly box:
Alternatively, I need to edit the URL, removing the oldid parameter.
I understand the idea behind the page title leading to the old version, but from a usability standpoint the lack of a link to the current version is a step backwards.
