I'll admit I have a love/hate relationship with Presto.
Yes, the app is very outdated with a difficult UX (user experience). I'm a web/mobile product manager for my main job and I've definitely seen better apps for design and user functionality.
However, the InstaShops are a great source of extra income for me and I have found a way to use both the website and app to get the full experience down for preparing, selecting, submitting, etc. I also do like how it shows the Sassie-powered shops and since I have accounts with pretty much all of them, I'll simply go to the MSC's Sassie-powered website and do more sign ups where needed.
Does anyone know when the new app will come out? I also wonder when the Sassie web platform will be improved? I'm guessing that comes next.
