Change Subscription?

I’m trialing an Basic Individual plan which expires sometime today 9/15/22.
I want to purchase a Pro Individual plan but when I try I am stopped with a message saying that I already have a plan. I stumbled onto the Change Subscription page but it doesn’t list the plan I want, only business/enterprise plans.

Do I really have to wait until my trial expires to spend money here or is there another option for Wappler to take my money?
