Brave reward problem

I have 15 bat but reward claim option is not showing anywhere.what is the solution?

Go to brave://rewards in the right hand side you will see an option to withdraw funds to your uphold account.
Note that the BAT shown in the purple box can only be withdrawn and the rest can be withdrawn the next month. You will need an uphold account to withdraw funds.
