This is a rant about how so many apps on many different platforms (TVs, mobile devices, computers, etc…) have decided to not actually show detailed errors any more. Instead, we get something along the lines of:
Oops, somehting went wrong. Please try again later
… and then, well, we get to figure out what just happened and what in the world we need to do about it. And good luck with that, since you have no idea what just failed.
Why software developers?!? Why have you forsaken us?
I agree that it’s (weirdly) uncommon to be the one saying “please give me more info about the error!”
A simple error code can be endlessly helpful (bonus points if there’s a corresponding support article explaining common codes)
Even if some codes are only useful to internal support, it’s handy to be able to search an error code and see “oh I can just jump straight to submitting a ticket/calling their support” or “oh, this fix might work”
