Groep app fails

I’m using a homey pro 2019 and lately the groep app fails when I try to restart it . The error messages are:

Invariant violation. Changing numColumns on the fly is not supported. Change the key prop on Flatlist when changing number of columns to force a fresh render of the component.

This is an issue with the Homey app, not the Group app. You need to contact Athom.

How??
