Seems to be an issue in purchasing Sketchup, all options. See below.
12:30pm - Problem confirmed on Brave, Chrome, and Edge.
@colin Are you the support I’m supposed to contact? 
4:30pm - Problem is persisting. Anyone else experiencing this issue?
2:30am the next day - Problem still persisting.
I wouldn’t be the right person to contact. I can check to see if people know there was a problem.
The page does take a while to load, but seems to be working at the moment.
11:00pm day 2 - Yes, it’s seems to be an issue still. But I will leave it to crank until it loads while I do other things.
Is there any chance my account has been denied access to purchase for some reason?
I tried in a private window, and although it still took a while to load, the shopping cart did load ok. Being a private window meant I wasn’t signed in, you could try the same, to rule out any issues with your account.
12:15pm Day 2 - Works when signed out, but when I need to buy it I need to sign in, and thus I get an infinite buffer wheel like the video. It’s been loading for an hour now.
I have asked Support to look into the problem.
Thanks @colin
6:00am day 3 - Still can’t buy SUpro 
You might want to clear caches and or history of the browser…
6:00am day 3 - Tried on multiple devices and browsers, even on the phone, clearing the cache and history = no dice.
Surely it’s not just me?
If 287 people tried and failed to buy SketchUp or renew their subscription, its $100,000 Trimble isn’t getting.
If this is happening world-wide, then yikes.
FWIW, I just tried going through the process of buying SketchUp. I quickly got all the way through to the point of paying with no trouble. I don’t know what it is that’s keeping you from buying it but I kind of don’t think it’s common .
7:30am day 3 - I’ve tried multiple accounts, multiple locations, multiple IP addresses, multiple devices, clearing the cache, multiple browsers, and nothing works.
11:30am day 3 - Just finished the prosses of attempting to purchase SketchUp in three different browsers, cache for all time cleared, in a private window. No dice. Spinning wheel of death.
There are several things that can cause this error. Our sales team can help if you contact us at http://help.sketchup.com/en/contact-support/sales-question/form
We are all at a conference this week, but we will help as quick as we can.
Does that mean you got things sorted and are now a SketchUp Pro user?
No it means I took his advice about contacting the sales team and am waiting to hear back on a potential fix
Ah … It’ll be interesting to learn what is hanging this up for you. Probably turn out to be that you aren’t holding your tongue right or something.
