Hoping to save others some aggravation. If you have an Android and your Truist Authenticator App no longer opens correctly and instead of opening a landing page instead opens a web browser to an error page that says "Hmm. That didn't work..." this is the LIKELY problem: You have developer options enabled. Apparently, the app doesn't like that (probably for security reasons). Go to your Settings, scroll all the way to the bottom area, and if you see "Developer Options", click on it and at the very top, toggle the "On" button to "Off". Then, your app should work just fine.
Nobody at Truist will know this; I only found out because someone in the reviews of the app in the Google Play Store put that information in his review (may he be blessed and have happiness forever). Hoping that putting this here on Reddit will save others the frustration I went through.
