National lottery operator Camelot has admitted to “a few teething problems” following the launch of its new web and mobile platform last week.

The multi-platform site was developed to work with smartphones, tablets and desktops. But some users have complained on that it “does not seem to be user friendly,” with one adding: “Have been trying to play online for the last two days with no success.”

Neil Kellar, director of IT and business services, said the overwhelming response from players had been “very positive.”

However, he acknowledged: “With a technology update of this size, it’s inevitable there may be a few teething problems, and users with much older devices may be limited in terms of their experience.”

Kellar added Camelot had implemented several “minor fixes” to the site so far and it had troubleshooters on hand, both online and via its customer contact centre.
