Wallet has been discontinued
Theres no mention of it here on the description page, but Acrylic Software have mentioned on their website that they have discontinued support for Wallet on iOS and Mac.
The core of this app is still functional as is (for which I give it three stars), but its not perfect and as others have mentioned some of its other advertised features have broken over time.
With no future updates coming from the developer, I cant recommend this software to others when theres a variety of other supported options available.
