Nun steht einmal Links ich soll vor dem 23.April 2024 kündigen und auf der rechten Seite steht "Kündige vor dem 10. Apr., damit dir keine Kosten entstehen."
p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
my german isn't great, but i believe the right side explains when your trial ends (usually 7 days) and the left side explains the date by which you must cancel to avoid a penalty (for late cancellation).
if you want to cancel but are unable to follow the steps described in the "how to cancel page", contact adobe support.
there are 2 ways to contact adobe; chat and twitter (now x):
chat: use a browser that allows popups and cookies, and click here, https://helpx.adobe.com/contact.html?rghtup=autoOpen in the chat field (lower right), type AGENT be patient, it can take quite a while to reach a human.
twitter/x: tweet @AdobeCare
p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative.
