Let's try a couple of things. First, reinstall the apps on both devices. Keep in mind that all offline music needs to be re-downloaded for offline use. Then, double-check again that all devices are on the same WiFi network.
If that doesn't work, make sure that:
All devices’ software is up-to-date. If you don't know, check with your devices' manufacturers for how to update the version software.
If possible, try switching between different networks and see if that helps.
Try using mobile hotspot to connect the devices to the same network.
If there's too many local files, try with just a few, create a test playlist with a couple of local tracks.
We also suggest that you go through this help article to learn more about restrictions and requirements on local files.
