Ads crash and I lose double rewards regularly. Can't log in to receive whatever it is I'm supposed to receive for participating in surveys. If you don't have Facebook, reward perks evidently won't happen for you. I have spent a ridiculous amount of time on this app for years, spending both free time and even time at work. I've spent money on this app (which is a large departure from my norm but I am truly addicted), but I'm just done at this point. It's probably for the best.
