I am not sure if this is an nvda issue.
Are there many of you use Libreoffice?
If there is a table in the Libreoffice writer file, when nvda focus on the table, e.g. press down arrow, nvda will not report that you have entered into the table
inside the table, if you move between cells, e.g. press tab, nvda will not speak about which column and row you are in.
