An infinite loading animation and similar things are very ambiguous. Is my wifi connection bad right now? Is the OS acting up because I haven't rebooted the device in two months? Is a server down/unreachable? This wide range of possibilities is very frustrating because it often means you have a long, unsuccessful troubleshooting session ahead.
