App crashes when I try to transfer between wallets – Spendio - Spending Tracker for iPhone & Apple Watch Review

Crashes without fail whenever I try to transfer between wallets. Not sure how to bring this to their attention? Otherwise app is excellent and just what I was searching for, a spend tracking app with a beautiful user interface! Just need transfers to actually work ?
