June 2026 Update - Dashboards performance issues

[KenBouchard]

We're seeing noticeably slower response times in Dashboards since the last update, particularly in Edit Mode. Now, opening a widget's configuration panel, take an excessive amount of time, making dashboard edits  much more cumbersome than before.

Is anyone else experiencing similar performance degradation since the update, or is it just us?

Yes!  Reloading to blank screens, super slow responses.  Basically broke everything on the AGOL update.

Yes! Category selectors in which I have multiple zoom targets set (three different maps) that worked fine before the update now cause my dashboard to crash.

Very infuriating how unstable this latest update has been, it's broken some other apps we have as well, and these are actively used by our clients.

Yes, noticed that too.
