I have had the same issue, almost a year now. Contacted technical support many months ago, they escalated and said things would be solved, and still zero progress. I have given up. Just snagged a screenshot:
To help, this happens regardless of if I am already logged in or if I try logging in directly from https://www.telus.com/en/qc/telus-privilege/registration, and happens on mobile and multiple browsers across multiple computers (even after clearing cache). This is clearly a backend issue.
