I agree, when It's part of the subject in test. I don't see any reasonable cause for a student to have to know about file types to submit a test, if that test isn't about file types. I don't, for example, expect my doctor to know how to convert an image file because that's not his job.
> The OP article claims "Spencer ... tried to convert it by renaming the HEIC file to PNG" which is not how you convert files.
This highlights the level of knowledge the users of this application have in this area. The developers should have made it Painfully Clear that uploading directly from an iPhone isn't supported.
> Maybe students learning that early on is not a bad thing?
I agree they should learn this stuff, but don't think it should cost them their grade to do so.
Now, I'm not saying that we shouldn't increase public understanding of these "slightly-technical" topics but I think we're a long way off and we can't expect that understanding just yet.
