This is just a strong suggestion, Unity Hub should be doing the check for the Editor updates itself. It is very annoying to run up unity hub, start my project (which closes the hub), just to find about that the editor needs an update, to then go to a webpage that just runs up unity hub again. This is a completely silly flow. Hub should have notified me an update was available itself and allowed me to download it immediately with none of the rest of these steps. And if by chance this flow is already available, it should be the default. I shouldn't have to hunt it down.
