I solve this problem by having a clean profile with only uBlock that I can open up when I want to make sure a purchase is going to work. uMatrix has a glitch where even when you enable something it sometimes won't work / load even when you refresh the page multiple times, but I don't think I've encountered problems on many pages with just uBlock.
