Top right corner, you will see your profile name, click it for the dropdown into profile. Once you click it it will show you a bunch of info, what you want is subscriptions. You'll see a scrollable bar just before your overview, roll through it and you will see your subscriptions as a tab you can visit.
Or if you prefer going direct what you can do is this. https://kbin.social/u/killick/subscriptions. Obviously anyone else would just change the username.
