Hey! I wasn't using my Mi band 5 for a long time, but my other watch broken and here I am back with my Mi band 5. I saw Lock screen in labs section and turned it on, but when I'm not wearing my watch it doesn't want to lock it self like the Mi band 4. The app is version 6.3.1 Zepp Life and the watch is running the latest 220.127.116.11 update. I have automatic Pulse reading on 1 minute but still nothing. The watch is running a custom resource called mi band 6 to mi band 5 theme. How could I fix this issue?
