When I am doing all the catchup Crafting Orders, I always need to deactivate ProfessionShoppingList to get access to the "Start Next" Button again.
Otherwise it is grayed out and each Order needs to be clicked and started manually.

PSL does support TestFlight in other ways, so I will keep this open as a to do item.
I am currently taking an extended break from the game, however, so I can't give an ETA on when this will be done.

Hello,
This looks to be an addon feature. Is this from TestFlight, or a different addon? If so, which?

Hi,
you are right. it's from TestFlight. Thought it was baseline.
