**Steps to replicate the issue** (include links if applicable):
Any diff view (on mobile) no longer shows the thanks button (since recent hotfix). For instance https://en.m.wikipedia.org/w/index.php?title=Wikipedia:Main_Page/Errors&curid=13207787&diff=1205708515&oldid=1205627551&title=Wikipedia%3AMain_Page%2FErrors&diffonly=1 shows the username, edit count, but there was previously a button for giving thanks.
Other places where you can give thanks, such as the edit history of an article still appears.
**What happens?**: There is now no "thanks" button on an edit contribution on mobile.
**What should have happened instead?**: the thanks button should appear.
**Software version** (skip for WMF-hosted wikis like Wikipedia):
**Other information** (browser name/version, screenshots, etc.):
Android - Samsung Galaxy S21.
