Issue with missing claim button

Hi, I enabled brave rewards in mid August on my Android phone (Android 9, Brave 1.3.1 latest updates. I accrued about 3 BAT by the Sept 1st cut off date. On Sept 5th, it rolled over to Oct 5th for the next payout date, so far no problems. But there was never a claim button for the 3 BAT I accrued in August. The BAT are still there and rewards for Sept are still accruing as well.

Is this a known bug or am I doing something wrong? Also, I was never prompted to back up like the desktop version. Overall, I’m very pleased with the BAT ecosystem, just wanted to make sure you guys are aware of this.
