One more question https://www.reddit.com/r/iOSProgramming/comments/1bbd06v/cant_update_live_activity/?show=original Found this post and after trying that I went through the same. WIFI works well but cellular doesn't work. Just want to know if I need to be worried about the network, or just focus on the priority

Wow thanks for the quick reply! I'm going to try different priority settings to find what works well.
