no new products are created and no photos are added

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

before, everything worked, the settings were not changed. even after checking the settings, it's the same, I don't know what to do anymore
