No lights showing in phoscon app (any more), but they are present in deCONZ and Homebridge

I am new to deCONZ and the phoscon app. I had started to add some IKEA tradfli GU10 lights and was impressed how easy that worked.

All of a sudden, after some days, my previous lights are no longer showing in the phoscon app. It says “No lights were connected yet.” They do show in the deCONZ app, they are also still manageable via Homebridge. I just can’t change them, remove them etc.

My Gateway version is 2.25.3, firmware is 264D0900, it’s a ConBee III.

When going to help/API and clicking on lights, nothing happens. All other API functions work however, and the DDF function in the phoscon app even shows the unique ids of the lights I had previously added.

]

The configured lights are also showing up in the Groups api function:

                    {
    "2": {
        "action": {
            "alert": "none",

            "8",

        },
        "type": "LightGroup"
    }
}
                    
                

When copying and pasting the lights API url into my browser, I get a response from deCONZ with my lights:

So where could the problem be? I have already rebooted the deCONZ VM. No change in behaviour. It happens in various browsers and in the IOS app.

What can I do so I can start adding lights and configure them?

It looks like there is a cache problem in the app.

When I uninstall and reinstall the IOS app, it works again.

Strange.

There is no way to refresh the app’s cache and I think that is the problem.
