Hello, Two of my bands use the xr18. I'm experiencing the following: 1. When switched to ethernet and running an external router, the iPads in the band sync to the xr18 but my Android tablet does not. When switched to wifi, my tablet works but the iPads do not. I always receive "authorization fail" when trying the correct log in w my tablet unless it's on wifi. 2. In the past, third party apps on my iphone link to one bands xr18 but not the sexond one. I've found several threads here and forwarded them to a band mate to assist but want to know whats going in as it seems like maybe an issue only the owner of the xr18 can correct? Any advice is appreciated.
