Is there any due date of GCP credit?

I’m curious that is there any time limit for the redemption of GCP credit from Round1?

#2

mine says it expires 28 May 2020, not sure if that’s a set date or depends on when you redeem. I can’t find the date of when I redeemed.

@karolisram thanks for the info!
