I had been using brave and had some BAT that I bought thru the Brave browser when I read that if you updated you would receive some free BAT. I updated and received the free BAT then when I returned to browser to do more research on how to use them I noticed that the balance was zero and the create wallet button was back but it is opaque and not clickable.
If I click on the brave payment tab it causes the entire browser to act buggy and If I get it to go to any other preference tab it will not return to the payment tab unless I restart the app.
OSX Seirra 10.12.6
Desktop Brave 0.19.123
( I have updated brave each time since the free BAT hoping that it would self correct with an update.)
