This definitely works, but I'm curious why we even have this retry_button context and the {% if ... %} check in our template.

Don't we always want to show a retry button on the retry page? Could we just remove this context variable and the template check?

@thekaveman Yeah I wondered the same thing. As long as this Retry page/template is not called from other methods, I don't think we would need the check. Should I just remove?

I looked through the Git history a little, and it seems like in 4c49895 we just forgot to remove if retry_button from the template.

Thanks for the find @angela-tran.

Yep @machikoyasuda I think we are good to remove this.
