Mini 2 Check-ins Not Received?

I have an Inreach Mini 2. I had 4 contacts that I was sending check-ins to today. Only 2 of those contacts actually received them. My brother and wife never got the check ins, and they usually get them no problem. I send the check ins from an Android using both the messenger app and the mini itself, whichever is within my reach first. This is the first hiccup I've ever had with my mini in the 9 months I've owned it. If I try to send a check in to my own cell phone I don't receive them either. The mini says they are sent and has a list of all sent check ins leading me to falsely believe they are actually received. The check ins are received over email no problem however. I reset the device and re downloaded the messenger app to no avail. No new updates are available. I did a successful Test message as per the Garmin website suggestions. Again, some of the contacts are recieving my check-ins, some are not. The last action performed on the device before my trip today was a mandatory firmware update, and I feel that may be the culprit. Does anyone have any solutions or ideas?
