Avast page: You cannot buy this item because it's out of stock

Avast Secure Browser Avast Secure Browser for Windows

This is the full message:

“You cannot buy this item because it’s out of stock
Another seller might have a comparable offer for the same item. If available, see all buying options and try adding to cart.”

The Avast browser is throwing up this message when I go to purchase items on Amazon. I log in with another browser and find two things:

  1. I can purchase the item with no problem (that’s on Chrome and Edge) and,
  2. The item has actually BEEN purchased but no confirmation page when using Avast, just that message.
  3. The item is actually NOT out of stock either.

So, it’s a conundrum. Has anyone else had this happen with the Avast Browser? I’m about to stop using it.

Thank you all in advance for your help!!!
