++ pending CI

CI mostly looks good but has two failures:

• 4 rewards unit test failure on Android. Will need to investigate this
• test-install on macOS failed

[bsclifton]

Re-ran - got the same 4 unit tests errors again. That includes these:

23:33:03  C  121.620s Main  [  FAILED  ] ConfirmationsRedeemTokenTest.RedeemToken
23:33:03  C  121.620s Main  [  FAILED  ] ConfirmationsRedeemTokenTest.RetryRedeemToken

I checked recent PRs merged and @mkarolin ran into this problem too when changing a string. This is not a new error- looks like we have some failing tests now
https://ci.brave.com/job/brave-browser-build-pr/job/maxk-new_tab-l10n/1/execution/node/552/log/

Should be good to go - but checking with @tmancey first

Shared above with @brave/releng - this may be due to recently updating Android to run tests using emulator. Going to go ahead and merge 👍
