Problems scraping webpage

I am having problems accessing an invoked webpage HtmlWebResponseObject object. It was obtained by:

PS>$webpage = Invoke-WebRequest -uri "https://www.grittv.com/tv-schedule/"

After trying to parse/inquire it with:

PS>$webpage.AllElements

it just sits there with a blinking cursor until I cancel it (30 minutes+ at one time)

Here are some investigations:

PS>$webpage | get-member

Status code returns 200 and OK

What is holding parsing up?
Can you help with invoking this data?

Also, it did work one time, I believe. I closed my scripts, came back another day, and it, since, just seemingly hangs.

Invoking on a second computer gave the same results.

Thanks
