Problem with casper mattress site

Hey all,
newbie and internet idiot here, just want to alert you to a bug I encountered.
i was trying to purchase a casper mattress online, got through several steps of the process then on “Step 3” “how do you want your delivery?” the options did not load. I tried several times, refreshing page, starting from scratch, tried contacting their customer support.

I ended up using another browser (boo!!!) to redo my order.
So I have my mattress ordered, but not through brave.
I have no idea what the technical glitch is or what to do about it, just thought I would let you know.
Using a Lenovo laptop a few years old running Windows 10.
I was running Brave on standard set up (I don’t know enough to customize anything…)
All my best to the Brave Community
