Google service logos are no longer clickable!
A reddit user has a genuine complaint. Google seems to have removed links from the logos of their various services.
The Google logo on search result pages and the Gmail logo in Gmail are no longer clickable.
These logos were a quick shortcut to the homepage of these services. Now you would have to rely on the top navigation bar which has gone through a design change itself.
It is not clear when this change happened but it surely is annoying for people who click on them on a regular basis to get to the home page.
