Activation code for Memories Plan not working

Hi, I bought a 1 year Nanit Insights - Memories Plan and received the activation code in my email. However, my activation code doesn’t work on my.nanit.com.

Steps:
1. I went to my.nanit.com and logged in with my credentials
2. I typed in my activation code in the ”Activation code” box
3. I added my credit card info
4. I clicked the “Start Your Plan” button to confirm, but nothing happens. I’m stuck on the “Activate Your Plan” screen. No activation confirmation screen appears.
