Dear Google duo,
I didn’t get any scratch …it’s even show all time that somethings went wrong…if u can not make solutions I uninstalled this app…
If you are having issues with rewards, I would read this here – https://googleduohelp.com/question/i-am-having-issues-claiming-and-earning-rewards-with-google-duo/
If you still have issues, theres a link there to submit your feedback for Rewards!
Hope this helps!
