Someone else just reported this as well. Please keep us posted. If there’s a resolution I’ll link the two posts.

If real-debrid is still active and your resolver settings are correct then I have two other theories:

  1. People have reported that the Xanax build is no longer supported. Maybe that is causing issues. As stated above, try clearing cache and data from Kodi then uninstall and reinstall just the regular Kodi (no builds). Install the crew add-on and set it up. See if links work then.

  2. Maybe you used a debloat tool at some point in the past? Perhaps disabling something in the settings messed up the firestick update? In which case I would do a hard reset of the firestick and start all over from scratch.

Also, see my guide on how to configure settings within the crew.
