Does it mean that if all my 10 referrals didn't check in the app I won't get the reward?

I have good news! ???? We have identified an automated claim process where you will will be able to claim on V2 of the app ???? The team will announce the release of the app. Hopefully the app store deploys the app quickly for you all to use. In the meantime, we are carrying out manual airdrops in order of those with the highest referrals, going down chronologically. Thank you for your continued patience ????⚡

Yes you won't get rewarded. You need to ask them to log in to V2.
