Why did they withdraw 20% and not 10% of the commission?

Question

Upwork

On the 15th (Tuesday) I received a letter that now 10% commission is being charged from client A and B (I have only two of them). On Friday (18) the money was transferred to Pending and took off the usual 20%. Why?

Answer 1

Everything will be fine from next week.

Answer 2

From the first $500 for each client, the commission is 20%, then 10% up to $10,000 further by % 5
(And it doesn’t matter what Pending is there now)

Answer 3

it is also written there when they shoot 20 and when 10 and when 5
in the help it is described with examples for completely dark people
