Bitrix managed caching does not work, the cache is not updated when data changes. What could be causing the problem?

Question

1C-Bitrix

In the Bitrix catalog, the caching type is set to Auto + Managed, the composite is disabled. Once a day, the data of the Central Bank on exchange rates are automatically obtained and the prices of goods specified in the currency are changed.
When the caching type is set (Auto + Managed), the cache of the catalog component should be reset automatically when the data changes, but this does not happen. Once a day, you have to manually clear the catalog cache to change the prices of goods.
How to solve the problem, set up automatic updating of the catalog cache after changing the data on the cost of goods when the exchange rate changes?
Perhaps mistakes were made during the layout and creation of Bitrix templates, what should I pay attention to?
