One way is to just browse your home feed and make sure you selected Subscribed or similar, here look at my screenshot: https://feddit.it/pictrs/image/55638b46-9172-43b9-9ec1-65831c92fbd3.webp. Also Lemmy.World is having some issues scaling so not the best choice IMHO for the main instance, bc it would be best a smaller and stabler one.
