It was working perfectly with Seedr until a few days ago when from all my video files only 2 are recognized. When I go to the files listing, I see that the others are grayed out. I tested the Webdav mounting with a different app and everything works normally.
Which device are you using Infuse on and which area in Infuse are you using to browse thees files?
If you’re able to send in a diagnostic report from your device (and post the code here) it would allow us to look a bit deeper into what may be going on.
