Some of this may because certain web retail platforms are being phased out, so the retailer is forced to change. The largest retail platform on the US is being phased out mid year 2020 so people are scrambling to find alternatives and convert. Running websites is never ever consistent. Code always changes. Stiff breaks. They get obsolete because the hackers are so good at breaking into systems.
Bottom line, these small retailers are TRYING to navigate technology (in an industry full of Luddites) and stay in biz. Not an easy thing to do.
