The gameplay experience, or rather the browsing experience, is quite similar to what you'd expect from the mobile app. You can scroll through your feed, like and comment on posts, and even use the search function to find new accounts to follow. The mobile version of the site is also touch-friendly, making it easy to navigate even on a PC.
One of the best features of using the mobile version of Instagram on your PC is the ability to use the site in a more compact format. This can be especially useful if you have a smaller monitor or prefer to have multiple windows open at the same time. You can also use the mobile version to access features that aren't available on the desktop site, such as the ability to post stories and use certain filters.
