Cannot get NotifyMe to work via the app

Mostly happy with Absa since opening my cheque account. I would like to, however, activate NotifyMe via the App only. It was working fine via SMS but I went into the Bedford Centre branch to try and change notifications to in-app. For some reason, the consultant showed me an error message when trying to change the notification method to in-app - something like "only eligible customers can use in-app." I just asked him to cancel NotifyMe completely for now until I can resolve this issue as I would like account notifications to only work via my app. He did send an email to the support team, but I would like please get a customer service representative who can take a look at my profile and rectify this for me as soon as possible.
