Minor update to the configuration app to bring in some bugfixes uncovered by your usage, as well as some tweaks to functionality.
Expanding amplitude thresholded recordings now allows you to set the maximum length of the resulting files. If a generated file would be empty then it isn't created, resulting in a smaller dataset.
Make sure you're using the latest version before making a post in the support forum, as the issue you're having may have been fixed in a subsequent update.
In order to use the new features added in versions 1.3.0 and greater of the Configuration App, you'll need to update your AudioMoth firmware to the latest version (1.4.0).
Apply the firmware to your devices using the AudioMoth Flash App.
