Trouble with Markers in iOS App

I am planning a longer cycling journey and have been playing with cycle.travel to learn the features and plan the route.  The tool is both simple and really powerful.

I am having some issue with markers, and I half suspect its user error.  I use the website map to create a route and on that route I can place, label and describe a location using the markers.  That all works great.  I save the map.

When I call up the map on my iOS app, I get the route.  Sometimes I get the markers, sometimes I dont.  When I do get the markers I cannot tap on the marker to get the name or description.  I see the marker (star, camera, coffecup) but its just an artifact, no information.

Today I cannot get the markers I set on 622415 (Cayucos-Baywood).  There are two midroute I set as a test.  They dont show in iOS.

Today I can get the markers I set on 624404 (Day 1).  All the markers appear to be there, but I cannot get their info from iOS app.

What am I doing incorrectly?  I've tried deleting/recreating, making them public/private/thisjourney....  This hasnt happened to me suddenly, I've had this issue for a couple of weeks, but I've been working on it intermittently.  I'd really love to get the info out of the markers, because ...  its pretty useful.  :-)

Thanks so much for any help.
