I have a big problem since yesterday : Whenever I try to use a label/tag in an advanced flow, the web app crashes… I tried to change browser, computer, to reboot Homey Pro, nothing changes ! For example, when I click on the gray label here : ![Capture d’écran 2025-11-23 à 12.40.25](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/0/c0bcd22dc03c5e2bf0ffe0956591d5eed32cbf2a.png) I got this : ![Capture d’écran 2025-11-23 à 12.41.44](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/8/98639f491730488451d12f7b35ac8e9e340b2f65.png) Any ideas ? ---

Since when do you have this issue? I think you should report it to Athom in that case ---

Which Homey Pro-version (e.g. 2023, 2019) do you have? What firmware version is your Homey running? Do you perhaps have the FlowChecker app running? ---

I have this issue since yesterday. I sent a message to Athom support. But I have to confess I trust the community more than the Atom support ! 🙂 @SunBeech : I do have the Flow Checker App running… Is it that app that may cause this trouble ? ---

Can you check if disabling FlowChecker resolves the issue? There was a prior bug in that app that caused issues with editing Advanced Flows in the web app. ---

I uninstalled the Flow Checker app, restarted Homey Pro… same ! ☹ Thanks for trying to help me ! ---

Sorry… I left this questions out : I have the Homey Pro (early 2023), and the firmware version is 12.8.2 ---

> [@Nlesdain](#): > > I uninstalled the Flow Checker app, restarted Homey Pro… same ! ☹ Too bad; Was worth the try 🙂 . What if you clear the cache of your web browser, so that you force the web app to fully reload (though I know that you already tried a different browser)? Other than that, I am out of ideas. Like others suggested above, you’d better reach out to Athom, via [https://homey.app/support/](https://homey.app/support/). ---

Ok…. I think I found what caused the crash… The guilty app is the “Mon suivi conso Enedis” App that conects french electricity meter to Homey so that energy consuption loads in insight. I will contact the App developper ! Thanks for your help anyway ! 🙂 ---

Good to hear that you found the culprit 😀 !
