Sorry for my beginner questions... I played around with the node Shopify app cli, but was wondering... everytime I restart the app process with "shopify serve", I need to follow the link stated in the terminal "* To install and start using your app, open this URL in your browser:" or hit the app up on the Apps page (which auto-logs in and creates a session). Otherwise my shop doesnt seem to be able to connect. I assume that is because there is no session anymore after restart. I feel that being a bit weird or maybe I misunderstand something...? What if the app is installed in 50 shops and my server restarts?
