no i dont get stuff from any other place than App store
Well when you open appstore, you see a searchbar, your apple-id picture, under that the word “discover” and links with searchphrases ready, and below that the word “suggested” and a bunch of apps, for example instagram.
lets call it appstore-startpage ! If I want to see more of the instagram app and i tap it, i come to the, what ?! App store instagram page !? Or as i did, i dont know, called it something like the instagram store/Shop inside App Store…
Anyway
you can browse around in appstore and just as on the startpage of App store you see apps showed everywhere in different assortments and categories, and the ones that you have installed displays “open” instead of “get” as apps you havent tried do, or “update” when available , But when i come across apps i currently use, and it says open but i click to go see that apps page in App Store, then it shows that a UPDATE IS AvAILABLE a second later
i have a screenrecording where you see it happen, here https://youtube.com/shorts/YFm_yGYtiV4?si=CG-N_rqhv8npIKzh. Its short maybe 30 seconds
