Search Feature Broken

Not 100% related but I didn’t think it was worth a new thread but I can’t delete the top two search history entries.

Is it also possible to either switch off tracking of searches and also trending searches? I’m not interested in what I’ve previous searched for and definitely aren’t interested in what other people are searching for.

Finally, in the app (iOS) it isn’t possible clear search history at all. Please can this be added?
