It looks like newer versions of Android encourage us to check "is this an unmetered connection?" instead of "are we on WIFI?" @vesta0 should we stick with "allow on WIFI" or change to "allow on unmetered"?

Good point @baron-severin Let's see what @betsymi thinks!

@vesta0 @baron-severin, @liuche included this in the 4.1 release notes, but I don't see any changes on Beta 4.1 or Nightly and the PR looks like is still open. Should there be anything to verify on this issue for now?

Am still working on unpacking this. For a future state, I don't think this is a simple matter of changing the strings we have. May need to make adjustments in the design to provide more clarity for users, particularly regarding Allow audio and video on Wi-Fi only. Does this means that audio and video will be blocked on cellular data?

@sv-ohorvath that was my mistake! I've removed it from the release notes.

Additionally. I tested the "Block audio and video on cellular data only" option and it seems that this option is not working. The autoplay is still playing even when I am on the mobile data.

I'm on PTO this week, @Amejia481 would you mind taking a quick look? This is the BZ ticket, this is the code that I thought blocked on cellular data.

The easiest approach here might just be to reenable our wifi logic. That should be super easy. Search in the project for 1621825 and you'll find comments about how to hook it back up.

No problem I can take a look!

@liuche FYI, this has landed on Beta 4.2 with a defect, see #8017 (comment). And there is #5636 as well.
