Several users of this board can confirm this statement, let's wait some time
I am one of those users.
All withdrawals I have made till now were processed once I clicked on "confirm" button.
A suggestion regarding the transaction fee:
Now, there are three options when making a withdrawal. 1. Regular, 2. Priority 3. custom.
If you select Regular or Priority, there is no way to know how much will be deducted from your withdrawal amount.
Assume that I want to send exactly X BTC to an address. I want a very fast transaction. I have no knowledge about transaction fee and I don't know how much I should pay as transaction fee if I select "custom" option.
Since the amount that will be deducted from the withdrawal amount is unknown, it's impossible to send exactly X BTC.
My suggestion is to display the transaction fee when selecting Regular or Priority fee.
For better understanding my suggestion, look at the image below.
