Hi. I got my first Apple Watch Siri 3 as a gift for Christmas. So far I'm loving it!! I'm still learning it. So I have a few questions. My first question is how do I close the apps out and how do I go to the app switcher? Is there a lock orientation? How do I turn the volume up and down with or with out airpods? Last question I got for now is what fun apps and games is there for apple watch? For some reason the Hatchi apple watch app doesn't work. Also. If you have any suggestions in general that will help. Thanks for any answers you can give.
