You're right — Instagram started answering the stories endpoint with a 500 on their side, which is why posts kept working. Version 4.0.5 handles it: the extension now falls back to another route Instagram still answers, so stories download again.

The update is already live. Browsers pick it up on their own, but you can force it from the extensions page, and please reload the Instagram tab afterwards — the download button only reaches pages that were loaded after the update.

Thanks for reporting it with the detail, it's what made the cause obvious.

Instagram broke that on their side — their stories endpoint started answering with a 500, which is why posts were unaffected. Version 4.0.5 is out and works around it by using another route Instagram still answers.

Update the extension from your browser's extensions page if it has not updated itself yet, then reload the Instagram tab. Thanks for the report.

That matches what we see: Instagram switches these endpoints off account by account, so one account is answered where another gets a 500. Version 4.0.5 tries the other routes Instagram still answers and remembers whichever worked, so the third profile should behave like the other two.

Update the extension if your browser has not done it yet, then reload the Instagram tab. If it still fails on that one account, open the extension and go to Contact — there is a Troubleshooting box there with a report you can copy and send us, and it names no Instagram account of yours.

Thanks — this is worth fixing, and you are right that it is not consistent.

The extension was taking the first entry Instagram sends and assuming it is the largest. That assumption turns out to be wrong: the list is ordered by encoding profile, not by resolution, so on some posts the first entry is not the biggest one. The next version picks by actual pixel size instead.

One thing to set expectations: Instagram itself serves these images at up to about 1080px for most posts, so there is a ceiling we cannot go above — what the extension can do is always give you the largest thing Instagram actually has for that post, which is what the fix is about.

Sorry about this — you're right, downloads were failing. A rebuilt version (4.0.0) that fixes the download errors has already been submitted and is waiting for store review; it will reach you as an automatic update as soon as it's approved.

Thanks for the feedback. Instagram has changed some of its APIs, and for some reason it only affects certain users. I'm looking for a workaround, and I'll fix it as soon as I find a reliable solution and have the time to implement it. Thanks for your patience!
