Sticky Cards/Treez Loyalty and Wallet Passes

Looking for insight on loyalty programs. Who do you use? Is wallet pass really the future?

We've cycled through a few in the last 10 years from buying stores and expanding. We're now at over 10 locations.

Our experience with Sticky Cards has been lackluster; however, we're using the branded "Treez Loyalty" version. We can't seem to get a straight answer on if we're missing out on the robust version of StickyCards or if its just this lackluster. There's not a lot of control for audiences and segments, limitations on dispensing coupons/rewards, and issues with it integrating with the Treez platform.

Anyone else have experience with Sticky Cards or other wallet pass based loyalty programs? What do you love? What do you hate?
