Can't find or recall how/where I enabled/disabled this, but it is off (my preference) for main account, but On for second account.

I definitely recall a patch note for some addon adding this when companions first came out but went through one by one and can't find. Unless I've mistaken default functionality for an addon, in which case I don't know why my main account has it disabled but 2nd account has it on.

Anyone aware of what addon toggles showing companion xp gain in the loot status bar?

e.g usually located lower right corner of screen, the loot status bar shows things like loot picked up, and brief flash of player +xp gain as well as faction gains like +10 mage giuld, etc when reading book. Above the +xp for player I will see +xp for companion Mirri or Bastian

Really want to disable this popup but can't figure out how I turned it off on one account but not another.
