I know that the Part “Third Party Apps Managemanet” is a known problem.
And lot of player dont have access to it, or struggling with loading problems.
I tried it too, and the page is also loading, and I cant create or autorize an app-id
I allready wrote to PG, and got the answere that this is a known problem, and team is working on it.
But is there a date? or a week? when this problem will be solved
