There is a permission change in V8.7 for gift cards.
In RPRO Area
Retail Pro v.8>POS
EFT- Activate Gift card
EFT-Deactivate gift card
EFT- Increase gift card funds (Add funds from what I have tested)
EFT- Force Authorize
Eft – See card number
I worked with one client who lost permission to add value to gift cards after a hotfix appt.
Turned out this permission was not set after the hotfix
