By web app, I believe the author meant apps served in a browser, not a mobile app made from html/css/js with a cordova/capacitorjs wrapper. Also, google has problems delivering functionality in general. Have you tried using google home? It never works properly for me, and for some reason I can't log in to my family's home with my google workspaces account. Most things except for search are a mess there, and search is getting worse as well.
