I’m in with you! My issues have been happening since the end of April and documented here:
My disconnects happen in waves. I was stable for a couple of weeks, but the last two days just after 12am my monitor has gone offline. 12:05 on Thursday and 12:09 this morning. I have replaced my router and I’m on my first disconnect “run” with it. I’m in California, so your 3:00 is my 12:00. I just find it strange that it mostly happens around the time it would do a firmware update AND there is never any backfill of data for any disconnects. Support tells me during each of my disconnects my monitor rebooted, but did not tell me why.
I fully expect another disconnect tomorrow as my monitor has not received the latest firmware update yet.
