For the past 3 or so days, at least once per day, I will load pawb.social and discover that I'm not logged in anymore. I had the same problem for several days about 3 weeks ago
I waited for the issue to reoccur so I could test that out. The jwt cookie is missing from the request to / but is present in several of the other resources used for the page. That's consistent with Crashdoom's comment. Sometimes, the issue would only occur in a specific tab (refreshing the tab did nothing, but opening a new tab would have me logged in), which is roughly the opposite of what that user reported, but this time, it was a problem in any tab
👋 This isn't just you! We're aware of the issue and believe that the latest version of Lemmy should fix it; It seems to be an issue with the cookies being set with Strict instead of Lax causing it to not be sent by your browser.
I had the issue reoccur, and I can confirm that the jwt token was missing from the request to /, but present for other resources such as the css stylesheet
