I am using Magento version 2.1.4
I added page title prefix and suffix (both just for test) in Admin Panel -> Content -> Configuration -> HTML Head input fields but none of them are actually renderen in pages. I di:compiles, deployed static files after changes, cleared the cache, reindexed, refreshed, everything but still no success.
I am writing my own theme but I have not overwritten title nor in layout xml files, nor phtml files.
The only head title that is showing in pages is the page/category/product title and that is all. No prefix, no suffix.
Is this a Magento version bug or I just have forgotten to enable/change something?
Update: I updated Magento to 2.1.5 version but the problem did not solve.
