Can't sign up for webinars without a company website

In the links you provide above, I don't see any fields where you are asked to enter a website address.

When several people tell you that your question is incomprehensible, you should rephrase it instead of feeling insulted.

I ran into the same thing TRYING to sign up for the AI asst webinar today.  i went through 5 chat agents to no avail. they were not comprehending the issue, even though i sent the link to the  registration  form. so frustrating to waste all that time.  Why should i be required to enter a website for my business in order to  attend a webinar in the first place ??      I am a small businss and don't  have a website b/c its an expense I dont engage in as I dont need a website.  I too pay $240/year for Acrobat Pro subscription, so it seems silly.  But what is sillier is that none of the chat agents could not even get what i  was requesting.  I think I was very clear.

Where can't you register? Your message is not understandable to anyone reading that.

You have PRO: Do you mean Acrobat DC Pro?

We need to have at least a link to a registration so that we can see what you are seeing.
