Ah!
Okay, figured out the problem, but discovered another problem, I think!
I am on Stripe Payment Addon Bundle 1.4.4, not 1.4.5.
However, WordPress says I have no updates. I’ve put a pic here showing how my WordPress site is saying Stripe Payment Plugin is up to date, but also, the payment plugin version is 1.4.4. I have updated the WordPress site fully too and it says all my plugins are up to date.
