I really, really hate all of these geo heuristics. Sure, don't advertise services to people outside of your market, I get that. Do ask for a payment method from that country too to provide your market-specific pricing if you must.

But once I'm a paying customer, I want to use the thing I'm paying for from where I am without jumping through ridiculous hoops!

The worst variant of this I've seen is when you can neither use nor cancel the subscription from outside a supported market.
