when updating the price list, after creating new products nothing happens, after some time the same products will be again in the linking table and will not be created, also photos are not added and are not updated

Good day
It is desirable that you provide examples with links to the system and products - this will help to solve your question.

I had a similar situation in my business, by the way, who is interested, this is my business https://fama.ua/podarki/nabory-dlya-vysky after updating the price and creating new products, the changes were not reflected immediately. Products reappeared in the link table as if they had not yet been created, and photos and updates were also not added. Solved the problem by checking the import settings and eliminating possible conflicts in the system. If you have similar questions, it may be worth paying attention to the synchronization settings or checking the system for technical failures
