Field formatter only displays file name not link to file I installed Drupal 8.3.5, no extra plugins or themes. I have added in the "base page" (structure/type) a field (file_in) to upload files.

If I add a new page (node/add/page) and also load a file in file_in (file2.txt), the new page displays me the link to the file.

Then I add a new field called file_ext as entity reference (file type). If I add a new page (node/add/page) and put in file_ext a reference to the file2.txt, I see the new page, but with only the label name of the file, not its link.

File module is enabled, version Drupal 8.3.5 (new and clean).
You should go to (structure -> content types -> page -> manage display):

/admin/structure/types/manage/page/display

and set your fields format and its corresponding settings the way you prefer.
