It says "Philippines is not your location, set it properly" but I am currently living in the Philippines and I'm Filipino. What's happening?

Are you using any VPN by any chance? If so, it might virtually change your location to another country.

Not at all, I even tried going out of incognito and set it in other browsers but that doesn't solve it.

I guess you should probably contact the site support, then. support@speedrun.com

Will do, thanks mate
