CAM PLUS order doesn't apply credit from 2020 Cam Plus (Black Friday Promotion)

In last year (2020) Cam Plus promotion, we got $3.75 service credit and a free V3 cam when purchased a yearly Cam Plus subscription. I can see that $3.75 credit in my Wyze Service billing history.

When I tried to purchase another yearly Cam Plus subscription today, I don’t see that credit applies to the order. Here is the screen capture of the order form.

Anyone able to apply/use the credit in their Wyze Service account?

The credit (prorated refund) is applied on the credit card right after the cancellation.
