You might want to provide more information. There really isn’t enough information to determine if the issue is related to the devices or settings you have or if it is a Brave Rewards issue.

Briefly describe your issue:
What Operating System and Brave version are you using ( Menu --> About Brave )?

What date did you verify your wallet?
Have you been able to successfully receive payments in the past?
Are you using a VPN? (yes/no)
