Storymap crashes on mobile/ipad

[NashvilleHighlandRimForest]

Publishing this storymap with several sidecars, on Safari on iPhone after the first sidecar, the storymap will force a refresh of the browser, then will will soon crash with a message : "A problem repeatedly occurred on https://storymaps.arcgis.com/stories/6763f0b7f81f4509bc51d080145039df" 

This storymap has repeatedly crashed in different points early in the presentation. I've taken the step of replacing all the sidecar maps in the presentation which were previously a single many-layered map with various layers visible for the respective slides with single maps with no more than a basemap, a county shapefile, a data layer and occasionally a sketch layer as labels.

One peculiar behavior is that one of the sidecar sketch layers is slightly transparent beneath the text box as one scrolls, and when the text box is passed, the storymap crashes.  "Our interconnected urban wilderness" is the slide that has the problem.

Testers have reported difficulty viewing the storymap on Android, and Ipad devices. My testing is on an iphone Max14 pro with IOS 17.6.1.  Safari crashes faster than Chrome, but both browsers exhibit the same behavior.

 Any troubleshooting help/recommendations would be greatly appreciated!  We're really proud of his storymap and are excited to share it, but obviously crashing mobile browsers and ipads is no bueno.

@NashvilleHighlandRimForest -- Hello! Great work on that StoryMap!

I'm sorry you are experiencing issues with your story not working as expected on mobile devices. I took a quick look and can see the issue. Some of the maps have a bit more, or in one case many more, than the recommended number of layers. Please see our guidance, here. The last map in your story has about 20 layers. The maps in the first sidecar have 5-6 layers, but appear in sequence, so several of them load together.

StoryMaps have a lot of logic that manages memory and resources to try to stay within the capacity of the browser; however, there is only so much that can be controlled. A story is still a single web page, and when there are several resource-intensive pieces of content (like maps, embedded apps, or large videos)being loaded at the same time this can cause crashing.

I do have some good news about this -- the underlying mapping technology that ArcGIS apps use is receiving some enhancements early next year to drastically improve resource management. We're hopeful this will have a big impact and alleviate many situations like the one you've reported here.

In the meantime, please be sure to remove any unneeded layers from webmaps used in the story. You can also try to separate maps and sidecar sections within your story with images or text to prevent them from being loaded at the same time.
