There should be a way to delay updating Fusion 360, or at least be able to run an outdated version when required. Currently, if there is a new update available, Fusion users are only given the option to "update now" or "quit". This makes the program nearly unusable if you are onsite with a client, and trying to show him or her your design since you are now completely locked out of the program until you find a wifi connection and wait for the massive update file to be downloaded and installed.
