What if Chrome had other bug that you can't work around? Users just would have to update it. It is that simple.
* Why do you think we can make our users upgrade? We're small, just one of dozens of websites they use per day. And in our line of business, this usually means losing clients (who, BTW, are usually not the end-users).
* How would we even be able to tell them they should upgrade if we can't test the version of their browser?
* It was Chrome 93 to 95. The bug existed for three months in all versions of Chrome. They couldn't update.
So what's the point of sniffing UA? What was your fix?
