I can't challenge other players to pet battles

[Gráinne-earthen-ring]

I see that here as well

Pet Duels why are they gone

Back in the day i had a lot of fun using my new pets to duel my guild mates but now it is almost impossible to find each other in the pet battle browser. i can understand that you could cheat some achievements but it would be easy to make those achievements battlebrowser only

I don’t know anything more. I don’t see anything in the Patch Notes about it/
