Inreach Mini2 "Acquiring GPS"

For some reason when i hike my Garmin Explore app comes up with a message saying "inReach Mini 2 Acquiring GPS". It often does this for 10-20 minutes meaning large portions of my hike are not being tracked, or so it seems. Weirdly, the inReach does seem to be sending tracking links. 

See the below images, at basically the same time.

Any idea what is causing this? I have tried moving the inReach mini around. I usually clip it onto the outer part of my rucksack. I also move it to the front and sometimes even just hold it. clear skies and cloudy skies it seems to keep happening.

Id love to know if it is a fault with the device or maybe just something i am doing wrong?
