Used to be great now very glitchy.. I tried 'claiming' 1300 points from an email they sent me but it kept telling me it had to be opened from a mobile device with the app installed.. I was using my phone. It can't see any e-receipts except Amazon even though my email shows successfully linked. Tried to take part in the brand game thing and it tells me to update the app even though I already did. I tried uninstalling and reinstalling and lost almost 1000 points for my effort. Glitchy at best....
