Experience Builder crashes on macOS / iOS devices when loading maps with multiple layers (works fine on Windows)

Hello Esri Community,

We are experiencing a consistent crashing issue with ArcGIS Experience Builder when accessed on macOS and iOS devices (MacBooks, iPads, iPhones), while the same experience works without any issues on Windows and other non-iOS platforms.

 

Issue Description

When an Experience Builder app contains a map with multiple layers enabled, the application crashes during loading on Apple devices. The crash can occur in different ways depending on the device and browser:

• On macOS (Safari and Chrome): the browser tab freezes and eventually crashes or reloads.
• On iOS devices (Safari/Chrome): the page becomes unresponsive and the browser force-closes or refreshes.
• In some cases, the device becomes temporarily sluggish, suggesting a memory or rendering issue.

The same Experience Builder app:

• Loads successfully on Windows (Chrome, Edge)
• Performs normally when accessed from non-iOS devices

Observations

• The issue appears to be directly related to the number of layers in the web map.
• Reducing the number of visible layers or simplifying the map significantly reduces or eliminates the crashes.
• No custom widgets or unsupported configurations are being used. However, we used the Scatterplot Widget and found some issues from other users especially when combined with Filtering.
• The web map itself loads correctly in Map Viewer, even on macOS/iOS — the problem only occurs when the map is embedded in Experience Builder.
• This suggests a possible platform-specific rendering, memory, or WebGL limitation on Apple devices when Experience Builder initializes complex maps.

Environment

• Platform: macOS and iOS
• Browsers tested: Safari, Chrome
• Builder: ArcGIS Experience Builder
• Map: Web map with multiple operational layers

Impact

This issue is limiting our ability to deploy Experience Builder applications to users on Apple devices, which is a significant portion of our audience. Since the behavior is platform-specific and not reproducible on Windows, it raises concerns about compatibility or optimization for iOS/macOS.

 

Questions for the Community / Esri Team

• Is this a known limitation or bug with Experience Builder on iOS/macOS?
• Are there recommended best practices for handling maps with many layers specifically for Apple devices?
• Are there any settings, layer types, or configurations (e.g., feature count, symbology complexity, WebGL usage) that are known to cause crashes on iOS?
• Are there plans to improve memory handling or performance optimization for Experience Builder on Apple platforms?

  Any insights, confirmations, or workarounds would be greatly appreciated.

  Thank you!
