WoW, Failed to create pet battle

I’ve recently gotten back into World of Warcraft. I’ve been playing without a subscription so my account defaults to a ‘Starter Account‘; which has certain limitations. Unfortunately one of those was access to Pet Battles. What is peculiar about this is that you can purchase the training et al. from a Pet Battle vendor, but you cannot engage in Pet Battles. Β This leaves you with the starter Pet Battle quest, but the inability to finish it. For the World’s most successful MMORPG, this seems like a glaring bug albeit a minor one, more of a nuisance for players getting into the game (or back into in my case).
