Issuing gift cards follows your role settings

Staff now need the "Record and change payments" permission to issue a gift card. Redeeming a card onto a client's account stays open to all staff. Owners can turn the permission on in Settings → Team → Roles & Permissions.

Staff — Issue Gift Card no longer appears for Staff until an owner turns "Record and change payments" on for them.
Redeeming — any staff member can still redeem a gift card onto a client's account.
Owners, admins and managers — nothing changes. If you turn the permission off for Managers, it now really stops them issuing cards.
Tips — still open to all staff, like the till.
