No Guide data on Android TV (TiVo 4K) w/o Internet?

I have the guide data fully loaded on my local server machine. But when I lose internet, All the guide data on my Android TV powered (TiVo 4Ks) lose their guide data info. Even though it can access recordings, channels from the server. The guide info is missing. Seems it will not work without internet. However this is when I use Channels DVR the most. Any fixes I can try? Thanks

I had something similar occur a few months back when I lost my internet connection. I expected to still see the guide data that had previously been downloaded, but I lost all the guide data completely until my internet came back up.
