I have built a really simple WebApp using ESRI's WebAppBuilder.
When I open the application, quite often (like 50% of the time) the UI doesn't load.
Any ideas what could be causing this?
The map data is quite complex, and does sometimes take a while to draw (10-30 secs), it's like the map loading causes the UI load to timeout.
I've added some screenshots (With details redacted) so you can see the how simple the webapp is.
