When I assign a manager to a location he can see all in other location while he do searching for a customer on . Please only show customers in location that assigned to.

Also, when he login to dashboard as a manager he should show only in his locations and customers in that location only as well.

All cards the customer subscribed to shouldn't appear to the manager only the assigned to him:)

It's a killer to my business, I have how a manger from a brand see customers' data and cards in other brand.

You don't allow managers to add points or redeem points in other locations it's great, but managers shouldn't see customers' data as well in other locations. It's very important.
