Brave Rewards stopped working on 1 out of 3 Pcs

Hi, I use Brave on 3 different PCs with the same Gemini account. Two at home, 1 at work. I even use my phone as an app. All good and fine, but as of today 16.06 one of my PCs logged out of Brave Rewards and states that this country is no longer supported. But my other PCs still function without any issues. I understand that regions were changed and Latvia is no longer supported? But how is it then possible that I continue to use it on both other PCs (all regional settings are set to USA).
