There are a bunch of heuristics on the server side that decide how long a license is good for on your client. Those heuristics change all the time, and will continue to change. Our intent is to make it so you never need to care how long your license will last - that it will be long enough for ordinary outages (plane flights, local connectivity issues, or server problems on our end). Also, setting up teams versus using an individual account changes the behavior. And having more than one license in either case also changes how things work.
Rather than trying to describe all the conditions and options, our goal is for it to quietly work in your favor if you’re within the license agreement. Please let us know if you see something happening that doesn’t work well for you.
