Enter the page at 8:00 sharp.
Cause by tomorrow, you can see it got greyed out for you the whole day till 8PM, then only the page got refreshed and the collect button is clickable. Though personally I never tried if the page will refresh by itself if we're waiting with greyed-out page, so I'm sticking to enter 8PM sharp trick. If you're ambitious perhaps can camp from 7:59 and see if the page will auto-refresh for you.

I camped the next day (day 2) at 7.59. At 8pm, the "collect" button becomes clickable but I got "failed to collect" message. Exited app to try again, it said coupon ran out.
The following day (day 3), I still failed to collect it. Keep trying and failed every time.
Day 4: managed to get at first attempt.
Day 5: the "collect" button showed "use now" because I had not used it. Manatau, at 8pm, it stll showed use now - it doesn't allow us to have more than one hero voucher, it seems

Wanna ask,
Q1: if I don't renew my membership and I only redeem my Week 4 vouchers on the last day of membership, will the voichers still be valid for the next 7 days?
Q2: Are hero voucher and voucher club vouchers stackable with
i) bank promo code (example SATMBB), or bank vouchers (the one we collect in normal voucher page),
ii) sale promotion voucher, say, 9.9 sale ?
