I know that a beta / but this product is definitely not ready to get launched, there are so many issues, there is also no option to contact the support, no Helpdesk. The point I hate is, it is not possible to publish a form without background, I do not unterstand why.
Preview for example does not work I use Safari on macOS I have no idea about other browser. Also it is not possible to use a custom domain, that a read flag for me.
