iPhone X here, running iOS 13.5.1. I have Google set as my search engine in Safari.

When I type sketch and press return I am taken to the Google Search results.

Notably, however, I have “Search Engine Suggestions” turned off in my Safari settings, and I also have “Safari Suggestions” turned off in my Safari settings. I’ve turned them off a while back because they were more of a nuisance than a help.

Maybe you and others turned those things off at some point too?
