Anyone having issues with the dexcom app?

I have a Dexcom G5 and I have been having a lot of issues recently with the iOS app. What is happening is it will randomly lose signal and I won’t notice for hours. I do have a receiver that I use as well so I don’t look at the app that often.(trying not to look at my phone in front of my two year old that often). The main reason I use the app is so my values are automatically uploaded to the dexcom website so my doctor can look at them. Is anyone else having this problem?

My app is up to date but the main problem is I lose anywhere from 6 - 9 hours of data. It usually loses signal in the middle of the night even though my phone is on my bedside table.
