Keep getting this message every single time I log on. I only have max TWW Alchemy with everything already unlocked. The only other Alchemy this character has is level 1 Classic Alchemy.
Double check that you don’t have levels for Dragonflight. Doing things such as Darkmoon Faire profession quests will earn you prior expansion levels after you’ve maxed current. It’s easy to level those and not realize. You might need to mess with your toggles to make sure you aren’t hiding Dragonflight.
I never trained DF Alchemy. I was an Enchanter/Inscription until TWW Season 3
