my PA is not assigning my production of the scenes i tried everything, any help?
How many studios do you have running? Do you have talent available and money in the bank to pay for the production? Do you have a director and equipment in every studio?
Assuming you have all that, make sure the PA has been assigned the production role and then go to the Auto Production tab on the PA's profile and adjust the global settings as needed to ensure it's allowing actors to be filmed (usually by lowering happiness minimum) and that shooting days are allocated.
Weekly production is allocated by the PA on Monday mornings so once you have everything up and running, you'll need to wait until the next Monday for it to implement.
All that being said, I've removed my Production PA as it was using the same talent too often and ignoring other talent, which resulted in a huge number of scenes being unable to be released due to popularity penalty.
