Hi, can you try spectating any race on your tablet?
Which devices other than a tablet are you having an issue with? If you tried on a phone, did loading the race viewer work?
If you still cannot access the race viewer, under settings, set the race viewer quality on the lowest settings and try again.
If you are loading the race viewer on wi-fi, can you try from a different connection, such as mobile data or a different location's wi-fi?
Hi Pedro,
Where does it get stuck in the loading process when this happens?
Also, could you try spectating a race using the spectate list on the home page to see if they work? (Edit: Just read Blunion's post, he already recommended it)
