Tagging @Mattches and @Steeven to check Brave version for Android.
According to Brave GitHub Android Changelog, the latest version is 1.42.86. The moderators can check to see when it will be updated in playstore and confirm if there is or is not a problem with receiving a claim button in Brave version 1.41.100 for Android.
For now, payouts are still processing. You need to wait until payouts processing is complete to see if you get claim button(s). Then submit a request for support to investigate any month(s) with payout issues.
If you dismissed the global pinned topic at the top of the Community forum, you can check payout status using this link: Brave Ads Payout status .
