Make your Yahoo-mail function well with wi-fi connections. Today it does not. Today one has to use a single 4g or 5g connection for the Yahoo-mail to function. If the wifi also is connected, then yahoo-mail stops. Both the app and by the web. That is an embarrasingly bad construction. And You have known about it for two years. If You cant get the base line to work, how are we to trust your higher skills - fex about safety. Because of this exposition in sloppyness I will uninstall Yahoo products. But it should rather be called Buhoo...
