@samartnik looks like this particular PR only touches a single file that's android only:

• android/java/org/chromium/chrome/browser/BraveRewardsPanelPopup.java

In cases were the only files that are being touched are a specific platform, in this case Android, you can use the following skip labels:

• CI/skip-ios, CI/skip-linux, CI/skip-macos, CI/skip-windows

Looks like the only remaining Jenkins failure is on macOS due to test-browser failing as per https://ci.brave.com/job/brave-browser-build-pr/job/pr5069_android_bat_points_text_fix_1.7.x/1/execution/node/594/log/.

17:35:57  [508/508] BraveRewardsBrowserTest.TipConnectedPublisherAnonAndConnected (TIMED OUT)
17:35:57  1 test timed out:
17:35:57      BraveRewardsBrowserTest.TipConnectedPublisherAnonAndConnected (../../brave/components/brave_rewards/browser/rewards_service_browsertest.cc:2762)

However, as per #5072 (comment), this PR only touches a single file associated with Android so there's no need to restart. This is also a known issue as per brave/brave-browser#8881.
