I'm new to creating web maps using data from our Esri portal. I created and saved a map this week spending much time with getting zoom levels correct to reveal the details of our water system as the user zoomed in. When I logged in today, I wasn't able to zoom to the same level of detail as I was when I created the map! Two of the layers won't turn on now because I can't zoom in to their visibility threshold.
I am using the Open Street map basemap, and hadn't changed anything from the time I logged out to when I logged back in and couldn't zoom in. 1:1,128 is the closest I can zoom in now. If I create a new map, I can zoom in to 1:71. But if I close and re-open, I can only zoom to 1:1,128 -- which doesn't meet our needs.
Thanks in advance for any suggestions.
