Has anyone actually made a mobile webapp that isn't a completely miserable user experience? People keep talking about how PWAs are the future or whatever but then every time I try using one the performance is really poor. Twitter for example claims their PWA "Loads quickly on 2G and 3G networks" compared to their native app but my actual experience using it was very much the opposite. Everything takes seemingly 2-3x longer to load.
