My Mail answer:
The "issue" is, that there is no larger plan. We have the yearly Pro Plan with maxed out 1.800.000 credits.
"Alternatively, we can cancel the current annual plan early, and you can start a new one when ready."
That sounds like a good idea. I was hesitating to do so, because I did not know if I break something.
Can I do the cancellation and re-purchase the max annual package somehow on my own? Or do I need you help here?
Hope to hear from you soon, and thanks for the support. I was a bit scared when "just purchasing the annual credits" did not work out yesterday :D
