I originally downloaded this app in 2022 and then uninstalled cause it said to contact support and I never heard back. I apparently forgot about this app until I was reminded about it and thought I'd give it a try. Lol. I downloaded it today and was reminded that I already have an account. I can't change my address or add my gender in the app. There is a section where you can connect various retailers, including Doordash and get points for those receipts. I had to connect Amazon, Walmart, and Target 3 times within 5 minutes cause they wouldn't stay connected. I tried adding doordash but it kept telling me that my login info is wrong but I even verified they're not. I sent cs 2 messages tonight asking about changing my address and about the retailer connection issues. I'm kind of scared to try to connect my other shopping accounts cause I don't wanna have to remind each one 3 more times. Klover does have a referral program to where you can get 2500 points if your friend signs up but I have no idea what the steps are to trigger the bonus, other than signing up.
All the copy ref link says is:
