Please fix this issue ASAP. ### 1/5 — App doesn’t work *2023-12-30* The app just shows a white screen when I try to open it. It worked when we first bought our water heater but I guess they gave up on the app and I have no idea how to adjust our tank now. ### 1/5 — Worst App Ever! *2023-12-27* Where is the customer service that should be provided? The last update was 3 yrs ago to fix a problem that still exists. ### 2/5 — White screen *2023-12-03* This App worked for about 1 year and now we only get white screen. We have the most recent version. What happened? Our plumber won’t call back and no response from Trutankless customer service. Did they go out of business? ### 1/5 — App is useless *2023-11-29* Says they fixed the “white screen” issue 3 years ago but they haven’t. ### 1/5 — The app just doesn’t even have a screen *2023-10-20* The screen is just white. How do you make an app this terrible. It’s actually just funny. ### 1/5 — From bad to worse *2023-09-30* App worked then failed and no support ### 2/5 — still getting white screen *2023-09-23* i’ve downloaded the latest version and I am still getting a white screen for login. should I be using different software to manage my trutankless water heater? ### 1/5 — No longer supported *2023-09-20* The app has gone from okay to worse and seems to have no support just like the company crickets and long long waits to hear from anyone ### 1/5 — Stopped working *2023-09-18* App does little but it use to work ok, now it just displays a blank white screen.
