To keep it concise: An improper date format appears to be causing unexpected file navigation behavior. As an example, when using the “YYYYMMDD” date format in the YAML and clicking on the Property date connection, a new file named “1970-01-01” is generated.
The date format follows the system settings of the device (see post below). Is there a conflict between using YYYYMMDD in your vault with the system settings used for parsing dates on your device?
