There was a bug in the editor: the preview area sometimes did not immediately refresh but required to calls of the refresh function. This error only happended with layouts defined as .xml files.
We published 20220207_2 as consequence.
There are no changes in the CaptainCasa runtime compared to 20220207.
we forgot to mention: when upgrading to 20220207_2, you need to update both the project and the tooling environment. (This is what we recommend in general... but typically you can use some older tooling version for new updates as well. Now you have to synchronize...)
