Little Zen One review for Linkpop

I used this app for over a year. It was fine until recently. I can't login. I reached out to two different support advisors. Despite telling them numerous times that I have tried logging in with my staff account, and owner account, and that it doesn't work for either - they still don't understand. It's been one week and the tickets are still open and unresolved. Unbelievable. 1. Shopify owns this app and doesn't recognize the issue. 2. Shopify Support has devolved to this abysmal level. Looking forward to a resolution, or at least an acknowledgment that the app is broken, quickly.
