Teams I no longer belong to still reappear in my Teams list

For several years, I’ve noticed that old teams I no longer belong to still appear in my Teams list. These are teams I initially created but later manually left through the Teams app. They show up in both Teams for the Web and Teams Desktop, affecting both Classic and New Teams versions. I assumed it was a bug that would eventually be fixed, but after about three years, they still persist.

I’ve tried clearing the Teams cache, browser cache, reinstalling Teams, and other troubleshooting steps, but the issue remains. It seems to be some kind of bug or persistent cloud caching. Even after leaving these teams years ago, they still reappear. When I click on one, I get an error message saying I no longer have access, and then it disappears, only to return within a day or two. Has anyone else experienced this issue?
