I'm currently trying to export a webmap to the instant app builder and just keep getting the message:
There was an error loading your resource. Please check all layers on the resource and ensure they are loading properly and then try again.
It prevents me from selecting a template for the app, or really doing anything at all but clearing the map off. There seems to be no obvious indicator as to what is causing the issue, and everything works well with the map in web map viewer.
Steps I took to try to fix this:
I completely removed everything from the map and it is still saying that a resource will not load.
I also opened a different map of mine and was able to get it to load into instant apps.
Any clue what the heck is going on here?
Most of the data is national weather service type hosted layers that have been tweaked.
