Xtra claims to offer... I quote:
'If you have Grindr XTRA subscription, you'll be able to view the 3 most recent profiles on your Viewed Me list, but you won't be able to interact with those profiles. (attached)
I paid €86,99 to discover this is simply not true. Grindr gave me 1 month 'Unlimited' subscription for my trouble, but for the following 11 months, I'll have nothing!!
