Issue:
You were trying to update the "ver_but_verify" localized string in the B2C "forgot password" flow, but the text was not updating in the view.
Solution:
You learned that you were missing the "ElementId" and added it to the localized string.
<LocalizedString ElementType="DisplayControl" ElementId="emailVerificationControl" StringId="but_verify_code">
You were able to resolve it thanks to the example in the "Localize the UI" documentation here:
If you have any other questions or are still running into more issues, please let me know. Thank you again for your time and patience throughout this issue.
