Casa OS Files App Connect to Synology


when i connect the Files App from Casa OS with my Synology Disk Station i only see the first folders but these are shown empty. Can some one please help me to fix this?

Thx a lot.

Did you use smb serviceļ¼Ÿ

I checked again and saw that only smb 1 and 2 were used. I activated smb 3 and after that it worked. Thanks for the idea with the smb.
