The earlier 'Square Check-in' has moved to my 'Reward Center'. If you're interested, remember to check in every week to earn points that can be exchanged for 'Token Vouchers' (which can be used to receive corresponding tokens) or 'Fee Refund Vouchers'.
If you want to earn points, you can also check out the 'Task Center' in the 'Creation Center' in the Square, which seems to refresh every week.
