Unable to insert a product in a quote

Hi,

in the last week end my company received the last update of Microsoft CRM 2015.

Now i checking if any problems exist.

The first problem I encoured was about the quote.

I insert the header of the quote and save the document.

Then when I pass to add the product in the line the SEARCH don't find any product linked to the Price List chosen (but they exist and are linked).

How could be happen?

Someone have the same problem?

Thanks

Luca

PS: I verify the same issue when I created a new Order and try to add a product to the document
