We need workers to continuously work when not online. Xbox systems cant handle being left on all day while afk like a PC can. The system could be similar to energy where it takes longer for work to finish when offline.

The workers do continuously work while offline, I noticed when I logged back in I got notifications about materials going to storage and workers leveling up

They don't they only finish the job they were on they don't repeat.

I wondered this same thing before the game came out. But BDO super influences to AFK train. For Pc what they did was make a minimize tray feature to use less resources of the computer. For xbox its honestly a 50/50 chance they are gonna change this or leave as is.

There is a repeat task option, but it does not work.

This was the most requested on PC for the last 3 years running. I'm still hoping they would finally implement it.
