Issue with Trådfri switch and integration menu

Hi,
IKEA trådfri is as usual not working very well, most of the time the lights don’t show as on when they are on. Right now my new wall outlet switch is reporting as entity unavailable but it is definitely available in the trådfri app.

I would like to remove the integration and add again, but nothing happens when I click the delete button in the GUI under configuration -> integration. How do I delete the configuration so I can re-add everything?

Anyone else experiencing issues with the new switches?

Solved it by using a web browser instead of the IOS apps.
