Experience Builder Not Loading

MT_JenAmes — Thu, 26 Feb 2026 14:51:18 GMT

I know there was an update last night, but this morning, my Experience Builder apps are not loading, at all. The EB starting page loads fine, but then when I click on an app to open in the editor, it loads the builder aspects, and part of a basemap, but none of the data in the map, and I can't actually interact with the page, can't edit the app, click on any of the items in the page, view it in live mode, nothing.

After multiple minutes of sitting, waiting, this is still all I have loaded of my page. The map and all it's data load fine in Map Viewer, but the app does not load at all.

If I sit staring at the page long enough, I get the "Page Unresponsive, Wait or Exit" notice from Chrome. I cleared my browser cache, with no improvement.

Is this because of last night's update? Everything worked fine yesterday.

@MT_JenAmes Just noticed this as well. We have informed our teams to wait it out this week since AGOL update bugs tend to get fixed soon. By any chance have you created a support ticket for this?

I haven't yet, wanted to see if it was a just me issue or an update related issue.

@MT_JenAmes @Dnaik , thank you for letting us know. Could one of you please create a ticket via Esri Support? To help expedite the process, it would be great if you could also share a reproducible sample here. Thanks!

I just called tech support about it. Seems like it might just be one/a couple of my EB apps. Case #04121828.

Thanks, @MT_JenAmes . We have identified the problem and are actively working to resolve it. We will provide an update once the issue has been addressed.

@alni, thank you for sharing the screenshot. The app loading issue is related to the Table widget. Since the issue you reported concerns the Chart widget, could you please provide a reproducible sample for us to investigate or create a ticket via Esri Support?

Hi Jianxia, I also cannot create a new Experience Builder app. Have attempted several times from a map as well as the Experience Builder App - Create New. All fail to create an Experience Builder app. Have tried several templates and they all fail.

I created a support ticket via phone on 2-26 for this exact issue, but so far, crickets. No updates and no response from ESRI. emailed them again this morning and nothing back so far.

I had the same issue but was able to create a few temporary builders for our users using the layer as a source rather than the source webmap. I of course had to exclude the map widget but at least they are able to access their tables for the moment.

AaronMannIFS — Mon, 02 Mar 2026 14:47:24 GMT

I did on the 26th. Case number #04121810

@CharGod @AaronMannIFS , Thank you for letting us know. The issue of not being able to create new apps has been addressed. Could you please help confirm if it is working for you?

Re: Experience Builder Not Loading

AaronMannIFS — Mon, 02 Mar 2026 16:54:46 GMT

Yes, that appears to be working now with a Map source selected as the data source.

Seems to still be an issue with existing builders that use a map as a source for some widgets.

@MT_JenAmes We have also encountered the issue with extremely slow and unresponsive load times. Loading the Experience Builder app directly rather than the version embedded in the webpage has been more successful but is still only intermittently functional.

Jianxia — Mon, 02 Mar 2026 17:09:53 GMT

@AaronMannIFS, We’re still looking into the issue with existing apps that include the Table widget and do not load or load slowly, mentioned earlier in this thread.

Re: Experience Builder Not Loading

AaronMannIFS — Mon, 02 Mar 2026 17:20:04 GMT

Good to know. Thank You! It has crippled most of our builders.

@MT_JenAmes and all, the app loading issue you reported has been resolved. Could you please help confirm if everything is now working as expected? Thank you for your patience and for bringing this to our attention.
