Dexcom Share App flaking out?

Is anyone else experiencing missing chunks of data during the night? My 10 yo son’s G5 transmits reliably to his phone, but my share app on my iPhone again last night has no data (no alert for that either, although it’s set up correctly to receive “no more data” notifications) for 6-7 hours and only shows a few data points prior to a low notification. Dex works fine all day but share drops out now often enough at night that I don’t sleep well anymore, don’t trust it.

I should clarify-- I am so exhausted that I am not tracking so well…
This could be a wifi problem, so I’m just trying to see where to start…
