I'm using Nothing CMF1 phone and I don't have the scan option on this device/app. I need that option to access something. I need this for my work. I appreciate your consideration and resolution in a timely manner. 🙂 fixed it

Company wide IT support is good for the app but it still has long wait times to register at time of issues. App works okay in general once setup properly. Can improvise on the user experience a bit
