A couple of years ago when I was trying to find official IPAs I used appcake. You probably want to grab an adblocker (preferably ublock origin) before visiting
Also, again, I recommend using SideStore (with on-demand activation in wireguard, which I've made a PR for) which will auto-refresh
Do you have payment methods on your Apple ID? Even if you don’t, you can try to switch your region on the Apple ID website. When it asks for payment method, choose “none”.
Omg! Why is it so annoying? Like I can’t even get one of my banking apps. I can’t believe that there is not a better solution as there are many people who live between countries.
