@tapanmodh technically this should still be in the 1.39.x milestone as the original PR landed in 1.39.x and this wasn't uplifted yet. Once brave/brave-core#12931 is merged into 1.38.x, the release team will move the issue into the correct milestone, in this case, 1.38.x. You can view/read the process via https://github.com/brave/brave-browser/wiki/Triage-Guidelines#uplifting.

So as per the above, I created #22182 and #22183 as follow ups. The fix from brave/brave-core#12852 has improved things on the phones but still seems broken on the tablet as per #22183.

@brave/qa-team keep in mind the above when verifying the above issue. Going to label this as android-phone-specific as brave/brave-core#12852 didn't fix the tablet case. That will need to be fixed via #22183.

[kjozwiak]

Above requires 1.38.87 or higher for 1.38.x verification.
