Hi,
I published my very first Typeform and was excited, to share it with friends. Unfortunately, when I try to open the TF-Link, I geht this message – also on different browsers or devices:

Does anybody know, what the problem is here? Do I need to get a plan first, to publish my TF?
BTW, I found several “dead” TFs like this in german language on the web.
Thanks so much for your help! I hope, I get this up and running somehow.
Jens
