I admit, I am using a real old, cheap Android phone. Doesn't have much memory for apps, but it generally works for me. Today, I tried to go to the iBotta app, and got a red screen saying I need to update. I am really nervous. I just went over $20, would be ready to withdraw funds. The screen wants me to uninstall the app --I guess so that I can install a newer version. I checked the iBotta website, and you can't withdraw funds via computer, only via phone. My question, do u think it's safe to uninstall the app? I am really not smart about smart phones. I only use it for a few shopping apps like this. I worry I will lose my $20. What to do?
