I am seeing the same problem. Villagers will not restock after several days. This is a full show stopper for my villager trading hall. I have built and used this same trading hall design in many worlds in the last several versions. I see similar reports being labelled a duplicate bug which says it is fixed. It is not fixed in 1.19. I would suggest holding off on creating 1.19 worlds until this is fixed if you rely on villager trading. It is very clearly broken.
