Popup windows no longer popup after April 2026 release install

Long time user…
The usual history graph that pops-up when a button is clicked, no longer works for me. e.g., a temperature entity badge use-to popup with a graph of temperature history. Now, no buttons pop up history on any dashboard across any platform - android or windows. In addition any button that should pop up a configuration window (e.g. thermostat) no longer work.
I have restarted and rebooted.
I routinely use the popup feature in my dashboards.
I run ha on an Intel i7 NUC with all the latest updates. I rarely have such troubles and I am stuck with how to fix the issue.
Any ideas?
thanks

Do you use the Bubble Card? There was an update today that mentioned popups.

I do but the issue is not specific to it. I’m not seeing the update to the bubble card yet…
Now I don’t get any response to clicks on updates in the “Updates” section…ugh.
Maybe I’ll do a restore…

there’s definitely a problem with 2026.4.0
I restored back to 2026.3.4 and everything worked fine.
Installing 2026.4.0 resulted in the same issue. Button selections don’t work.
Even in the updates section, I can select a pending updadte - I get no response to a mouse click. Problem exists across client OS platforms and various browsers.
Now what?

I have the same probleem. No popups on mobile device(3 phone dit brands, 2 tablets) cant update. Cant open colorwheels or histor data, camera streams in media map. Not only on dashboards but trough the hole app.
Tried reinstalle, tried change phone setting.
Strange the fact that it happen all at once on all phone.

Only works trough webbrowser on pc. Tried webbrowser on phone. Also no popups

I have the same issue where the typical HA popups are not working on PC or phone apps. Posting to follow. [Will probably roll back]

With the help of Gemini, I have fixed the issue by removing all the old .js files located in /config/www.
The files included: grid-view.js, group-element-bundle.js and card-mod.js. All with dates going back to 2021. I must of hand installed some card elements when I was experimenting with dashboard elements.

Now my dashboard related .js files are almost all located in /config/www/community. This is the default location for hacs installs and maps to /hacsfiles/… Although I’ve noticed that some .js files end up in some other random, non standard locations, e.g., /bambu_lab/ha-bambulab-cards.js.

In any case, any dashboard .js file should be under an automatic update mechanism to keep it in sync with HA releases.

I can confirm this solves the issue
