June 2026 AGOL Update - issues....so many issues

[GrantHoward1]

Where do I start?
Field Maps access issues - but somehow only affecting some users. And somehow only affecting some maps. And not data layer related, because I can duplicate the map and then affected users can use the new map. Not cache related, because issues persist with using a device that NEVER had Field Maps previously installed.

Then, I just find out that my editing tools in some Experience Builder apps is not working. The editing tool is selected EVERY layer in the map, even when they are turned off. And those layers are not even editable/selectable in the first place!

So tired of ESRI treating their customers as the sandbox environment for their updates.
And yet, ESRI Health Dashboard is all green showing no issues. But here on this community board it's full of users with random issues after June 2026 update.

Please fix it all! Or we'll have to be telling our field staff of over 100+ to get paper and highlighters ready!

Also experiencing strange issues only after this June '26 update. I've a client whose hosted feature layer is not displaying properly in their web maps with filters applied, even though there is data that matches filter conditions. You can get it to display for a second by clicking on the layers and bringing up the layer configuration pane, but then it disappears again. 

I'm also seeing strange behavior of ArcGIS Notebooks. WAY more frequent disconnection and the kernel dying. It is very frustrating.

If you can share that web map where you are seeing the filtering issue I can take a look. If you cant share it publicly you can invite russell_jsapi into a group and I'll take a look.

Just adding to the list - but with a work-around as well.

We noticed that after the June 2026 AGO Update, some the Layer filters in the Maps would get incorrectly formatted when editing the filter via the Map interface, which is what we've always done.  

A query that had more than 3 conditions, like the following:

(field1 = 1) AND (FieldCount1 <> 0 OR FieldCount2 <> 0 OR FieldCount3 <> 0 OR FieldCount4 <> 0 OR FieldCount5 <> 0)

Would get formatted to:

(field1 = 1) AND (FieldCount1 <> 0 OR FieldCount2 <> 0 OR FieldCount3 <> 0 ) AND FieldCount4 <> 0 AND FieldCount5 <> 0

As a work-around we stopped using the filter via the Map Interface and use Arcgis Assistant to edit the definition expression in the JSON Editor.

If you can share a map showing this issue I can take a look. You can invite russell_jsapi into a group and I'll take a look if its not shared publicly.

I've created a repro case and looking into this.

Late to the game on this, but it seems like dashboards have been taking some hard hits. We are experiencing a niche issue with custom basemaps not displaying at all in our dashboards. They are visible in the web maps when saved, but will not appear in the map widget in the dashboard. If we turn on the basemap switcher widget and select the custom basemaps within the dashboards, then they will display.

Conveniently, ESRI created basemaps appear just fine. Tried in incognito, clearing my cache, checking the projections, ...all the usual troubleshooting issues. This is SPECIFIC to just the interactions with dashboards.
