If the host name included in the URL of the PWA and the host name included in the URL of the xlsx file accessed from within the PWA match, the upper menu portion of the application selection screen for opening the xlsx file will be blank.
However, if the host name in the PWA URL is changed from the PC name to an IP address and the host name in the URL of the xlsx file accessed from within the PWA is left as the PC name so that the host names do not match, the upper menu portion of the application selection screen for opening the xlsx file will be displayed. (e.g., the Safari icon appears in the upper right corner).
Is anyone else experiencing the same phenomenon? Is it a bug?
