Hello. I, too, am adding a bug report onto the pile. I've read everything in this thread since January 1st so I'll start by posting diagnostic logs and environment info as the developer requests.
Environment: I use SMB only, use standard Share permissions setup by Unraid (no chmod or chown commands), ensured "Hide dot files" and "Enhanced macOS interoperability" are set to "No" while "Enable SMB Multi Channel" and "Enable WSD" are set to "Yes". In the Recycle Bin settings I ensured it is enabled and running with hourly emptying.
Behavior: Deleted files are not appearing in the recycle folder on both cache drives and array shares. The issue started since upgrading to Unraid 7.0.0. I have tried many combinations of troubleshooting in attempt to find a pattern but the Recycle Bin plugin seems to do nothing now. The thorough "reset" method I've tried is uninstalling the plugin, manually deleting the recycle folder from all shares & drives, rebooting Unraid, reinstalling the plugin, configuring and starting the plugin, then testing file deletion on the array and cache drive (via SMB). No luck, in fact the plugin did not recreate the ".recycle.bin" folder anywhere.
If you need more info or for me to test something just ask.
