Why can't I see aircraft details now in FR24? (at least the first two lines of data?)

I have noticed today that the fiels to view additional information about aircraft in FR24 have been greyed out and all I can see in the defaukt view is just aircraft icons but no flight details (flight number, flight level, registration etc). Not very helpful. Does anyone know when and why this has been done or is it just my view? I currently use Chrome to view FR24 and have been using it for over 2 years quite happily until today.

Any feedback, ideas welcome. :confused:

Cheers
