New Map Viewer keeps crashing!!

[neomapper]

I created a new map thinking the constant crashing and unresponsive page would stop but it's constant!! Any ideas??

Try opening your browser's Developer Tools and watch the Network tab. See if there are particular requests that are taking a long time or a lot of memory to execute.

Does this happen with other maps, or just that one? It may be related to the layer. We have a couple of big layers that can really slow down, even crash the browser.
