I noticed my response linked in a bug report thread:
https://us.forums.blizzard.com/en/wow/t/pet-battlecollection-broken/681040/116
So I wanted to provide some additional clarification/updates -
When pre-patch launched, we saw some issues with the account services that grant account wide things. These things included (but not limited to):
- The additional backpack slots for having the authenticator and phone notifications enabled
- Account wide mounts / pets
It was initially suspected that this played a role in the Battle Pet Cap being lowered after a character service.
The bug on this has remained “Open”, so I need to make an update to my previous statement. It may still be possible for this to occur. But, if you are affected it is something the Game Master team can assist with.

I’ve seen, mixed in with the pet collection conversation, folks talking about other account wide elements - like toys, or account wide quests like the intro to pet battles. Those are separates issue but they have been reported for investigation.
