Okay, I have completed my tests. The browser I am having issue with is Slimjet. It is a Chromium-based browser. The extension that is not working properly, is Flag Cookies. The Mozilla/Firefox version of Flag Cookies is working properly, as tested on Firefox. Back on Slimjet, EditThisCookie is detecting and exporting all relevant cookies, and JD cookie login is working properly.
When using Flag Cookies on Slimjet, the extension is failing to detect a few cookies on Instagram, one of them being the sessionid you mentioned. Also, a little while after the page has been loaded, Flag Cookies fails to detect any of the cookies.
At this point, I am not sure whether this is solely a Flag Cookies bug, or whether Flag Cookies is having issues only on Slimjet. If the Flag Cookies extension downloaded from the Chrome Web Store is bugged, then everyone using a Chromium-based browser will run into issues such as this. The Chrome Web Store version of Flag Cookies was last updated on June 30, 2022.
