Hi. After upgrading our S100 to firmware version 18.104.22.168 the Auto Cleanup feature has stopped working. Our PBX even sent us an email warning about "Storage Full":
[2020-07-15 15:22:54] The available space of NETDISK is running out. Total size: 32.00GB, Capacity Available: 1.60GB.
We had to expand the available storage space to avoid issues with call recording, that's why in the following screenshot our NETDISK has a larger storage capacity.
We have not tested reverting to an older firmware version, but we suspect about the new version as this was the only significant change we did on our PBX on the last weeks (aside from managing extensions, routes, etc).
