Documenations is misleading.
In first paragraph it says "No. We have a free tier with no limit on the number of players."
And in on of next paragraph "PlayFab is free for all customers up until 1,000 players. Once you hit 1,000 players, you need to pick a plan."
So, please update documentation with right options and without contradictions.
