Regarding the telegram app I’d check iOS settings->apps->telegram->search and make sure “show app in search” is checked

You can intentionally hide apps from search. If you did this, it’s not very obvious that its hidden from search unless you dig for the setting. Similarly, “hidden” apps refuse to show up in search results anywhere, even in settings.

Thank you for this, I have wondered for more than a year why Google Maps would not show up when I searched for it.

Thank you. I wonder how that happened as I was not aware such a feature existed.
