1.5.12 got released last week and these are the changes that are made to this version of the firmware:
[Settings] Fixed a bug that could prevent the world map from loading
[Z-Wave SDK] Fixed a bug that caused multiChannelNodeId to be undefined
Note: In some rare cases, 433 and 868 communication may cease to function after installing this update. Disconnecting Homey from the power supply for 30 seconds resolves this.
If you did not receive the update, you can manually via Settings > Updates.
Keep in mind that this topic is not the place to report bugs or request new features, this has to be done at the Github of Athom.
