So now cashback reduced from up to 5% to 
2%
and still no proper update on Jupiter app for card.
Even no proper details for which categories or merchants are applicable for what percentage of cashback and i think within few months cashback details are updated so now i think this is not trust worthy sign.
Just keeping wrong advertisements and gain the public interest.
