I am having the same software problem. I use Apple iPhone as well as a Microsoft Surface. Last Saturday Jim flew 12 hours in wave and thermals. Both devices had same difficulties. The InReach default seems to be "all time" and a really tight zoom which is ludicrous for an aviation plan. I get the current blue arrow, then expand the view (which is DOWN not up on the iPhone ) with SINGLE taps on the left hand side scale bar. ( I don't use the typical pinch/push on the map as it "throws" the map to unknown places!)

Heres my "workaround." I click on the Map Filter, then use the "Date &Time Range" pull down of "most recent track." Unfortunately, it doesn't refresh automatically (factory rep says they are working on it). I leave the (desired) scale, change the filter pull down to "all time," let it update the page, then change the pull down filter back to "most recent track." It will be updated. Hope they get this fixed soon.

I do like to see Jim's altitude. When you see 2000 AGL on a wave mission it's time to hook up the trailer. The speed seems to be instantaneous so it could be slow thermaling or parked in the wave climbing. You can get a overall speed from the top left hand "all users" tab.
