when i opened my reward settings and copied of my account brave://rewards/ link and paste in other tab of brave browser it’s shows as chrome://rewards/ , i confused is it a bug or what ?
This is expected because you are never promised a BAT token grant for downloading and installing the browser in the first place. I am not sure where you may have heard this. (Perhaps on a third-party airdrop website?)
We often offer promotional grants, but supplies are limited and it is on a first come first served basis. Just keep using the browser and watching for a notification for the next round of grants. This is usually once per month, but there is no strict schedule.
