Earlier quoted context omitted.
The question is what the cost of that fix would be. Once the ticket reaches the developer it's probably quickly done and pays for itself with a handful registrations. However getting from support to a developer is the complex part. (Support has to understand the issue and then it has to be routed to the correct team ...)
I completely understand why you see this as a 30-min fix, and therefore they should just knock it out. That's not how they would likely see it. If their devs are 100% utilized (which I'm sure they are), then fixing any issue -- even a 30-min one -- is going to mean that a different issue is delayed. The question becomes this: at what point is fixing this issue more valuable to the company than any other issue the sam…
This has not been my experience.
If you work at a company where it's possible, I strongly suggest shadowing a supporter for a day. You'll leave with a 5 page long rage-list of issues that weren't adequately captured (and would take you a few minutes to knock out) and a new relationship established that will help unblock that bottleneck of information flow.
IME, this is in part because supporters aren't as familiar with the technical aspects and don't know how to frame the issues they encounter in a way that would get traction with either PMs or engineers. As such are not well prioritized relative to issues that are fleshed out technically. I've worked at a company where supporters were spending huge amounts of time resolving issues that I knocked out in 5 minutes after shadowing and materially improved their operational efficiency.
In a word, what's missing is a culture of ownership.
