Ads not available in the region

Hi! I am getting this message when I try to watch the ads and claim my rewards: Sorry! Ads are not yet available in your region…
Why is it happening? I am from Serbia, and I checked, it is on the list of supported countries. Can you please explain to me what is wrong?

@CryptoNikki,
Thank you for reaching out to us.
At this time, we’re experiencing some concurrent issues with our Rewards/Ads system on our end. We’re working to get them resolved and I imagine that the message you’re seeing will be removed.
Thank you for your patience.

Alright, looking forward to it! Thank you for replying so fast!

@CryptoNikki,
You’re very welcome. Out of curiosity, can you tell me what version of the browser you’re using at this time? You can find this by going to Menu --> About Brave

I am also a User from Serbia, using Brave and talking about it to friends…
my version is Version 1.3.115 Chromium: 80.0.3987.87 (Official Build) (32-bit)
