Apple Watch app starts with random lock

For a while now, the Watch app always starts with a random lock. I use the latest stable versions of the app and iOS / watchOS. Sometimes one lock is displayed, sometimes another. Previously, the app always started with the first lock (from the left).
Has something been changed here?

The Watch app should start with the last lock used and always did so.

There was a bug with the introduction of iOS15 which caused this behavior not to work. We released a bugfix for it that solved the issue (for almost all cases). It will be finally fixed with the release of the new watch app which is in beta since before Xmas. You can try it by joining the iOS beta program.

Thanks for the info. The problems only occur since iOS 15. I will test the beta. Thanks!
