Not to excuse the non-debouncing behavior, but I wonder how much of those 15% are an actual loss, since it’s limited to users who are not interested enough to try a second time. I’m not denying there’s an actual loss, but it may be significantly less than the nominal 15%, and it would be interesting by how much.
Theory of mind error here. If it doesn’t work I may assume their system is down or doesn’t support my browser. Thus there would be no point in trying again, even if I was interested in the product. If it were to work on the second try it’d still be a sour taste - bugs are not a good first impression. At least personally I would have suspected the SaaS company as opposed to Google.
If I was truly interested, I would try again in five minutes or an hour, or from a different browser/device. Errors are caused client-side often enough.
