Morning i ve started use brave occasionally last year, i put 6 Bat in the wallet but after new update i lost these.Is possible to recover the Bat?

HI @MicheleM could you DM me the information in your brave://rewards-internals and I can try to investigate? Thanks.

Hello, I have only this information: I send 6 BAT in Date=Mar 15,2019 at 10.57 AM from coinbase.
the wallet address:
0x78BcD6219BD66Cb3fE1a4b5BEc9edba83D67DD79.
Is enough for start a research?
Thanks a lot.
