brave://rewards-internals shows wallet is no longer connected.

@Mattches @steeven do you have any idea what may have happened and why my wallet is no longer linked? Thanks.

Please send me a DM with your wallet payment ID, found on your brave://rewards-internals page.

Thank you.

DM sent. Sorry for the delay.

A mi me esta sucediendo algo similar en la tablet. Recompensas desaparecen periodicamente. Incomprensible.

@Mattches , my wallet is still not connected.
