Four noobs with InReach Explorer+ are experiencing delayed message delivery (hours). Unsettling since reasonably quick messaging is expected and needed. I expected rapid (minutes, since that's the setting on the devices) delivery/receipt of messages, in particular from InReach address to InReach address, ie what I assume is "satellite direct" messaging. Is that an invalid assumption? Not surprised that email or text message delivery might be delayed, due for example to being off-grid. I assume cellular connectivity must be operative for message delivery via those systems. Garmin has extremely little useful info on their website and no link to contact them directly, hence my query here. Found nothing relevant on Advrider when I searched here prior to this post. Any insight appreciated.
