[Membership 2 Pro] Stripe Subscription Error (sandbox)

I get the following error when test purchasing a membership subscription with the Stripe subscription gateway.
Error: No such plan: ms-plan-355-1snSKZXNXx8fvFFxRslt4u
The user is created within the site and in my Stripe customer list but the subscription is not created and payment not made.
Does the plugin not create the subscription in Stripe? I tried manually creating the subscription in Stripe using the ID from the error message but this didn\'t work either.
