@stevang I believe there’s flags for it you have to activate. Always show Brave Rewards custodial connection options which is at brave://flags. Otherwise it defaults to what it shows for everyone in your region, which is that Rewards are not available in your country or whatever, which I think is what you’re showing me.
At least you can give that a shot and see if it lets you connect, assuming it’s the same exact browser and Rewards profile that has remained connected until now.
