I'm still a little shook that twitter's response to my offer of detailed resources to reproduce their SW bugs was "file a ticket with Chrome". Love the blame shifting. Yes, it is a broken tech. But to literally not care that your choice to use that broken tech is breaking users?
So far tonight I've hard refreshed twitter on Chrome 4x to fix the service worker. It happens so often I practically have rewired refresh to command+shift+refresh. At least Chrome at this point kills the SW with a hard refresh, Safari doesn't.
