First Citizens Bank app works when you enable a setting.

In a Google Sandbox, I got First Citizens Bank app to work when enabling: "Automatic exploit protection compatibility mode" in "Settings > Apps > See All X Apps > FCB". I can also confirm Zelle works within the FCB app as well.

I usually just use the web address version of the bank, but yesterday noticed that Zelle doesn't work within the web site of the bank. So I tried enabling this setting for the app as recommended on this site for certain apps(mostly banks).

Xarcell Yes, when an app isn't working usually the first thing to try is exploit protection compatibility mode. Most apps that crash on GrapheneOS will work with the compatibility mode on.
