The original poster has not reported back, however this is the expected behavior when the following has occurred:
- A sufficiently large number of file/folders have been copied to the MCH
- or A Clear device settings has occurred.
What is happening is that indexing the MCH is a slow process and changing file permission on a lot of files and folder is also a slow process. The files can be updated nearly in real time in the SMB and the Debian files system on the MCH, but updating that information to the webapp will take some time.
reset local permission
no loss of folders, but changing permission can take tens of minutes where the folders don’t show up in the webapp.
folders begin to reappear after new credential is set via ‘enable local access’.
