Routes not saving!! Very Frustrating!!

I have a Garmin inReach Mini, and I am trying to programme routes into the map using the map tab on explore.garmin.com. I spend a few minutes putting the route onto the map, name it and save it only for the page to refresh and everything I have done disappear. The routes are not saved. This does not happen every single time, maybe 50% of the time. Incredibly frustrating. Help!
