Consider conducting a digital detox at first. Just delete the application for a month and observe your behavior. In case it turns out that you keep reaching for your phone to check your updates without noticing this habit consciously, then you will know that this application has turned into your addiction. For most users, by the end of a month of absence, they no longer care about the app updates.
