Thank you for posting this news. When I check for updates it was there, then a few hours later the update was gone. My thinking at the time was, what have I done wrong ? And a bit later I was like was forgetting there really was an update to 2.4. Now reading this news explains it all. I will update my Xiaomi Mi 5 (gemini) to /e/ OS 2.4.1 today. I just checked I have it available. So thank you for fixing it.
