Cannot claim bat rewards on iOS

Cannot claim Bat rewards on iOS, cannot sync my uphold account.

A notification appears telling me that my reward could be claimed.
After touch that notification, a sync error appear.
Now it say in the brave rewards icon “grant “ ( i guess because i’ve got the explorer in spanish)
It doesn’t give me anymore the option of withdraw

**Expected result: get my bats **

Brave Version( check About Brave):1.19.2

**Mobile Device details: iPad **

Additional Information:

At the moment claiming rewards are not available in IOS. I have an ipad so I am waiting since june 2020 .
