Hi @HaraldP,
Welcome to the Dyson Community!
Sorry to hear about this - it sounds possible that the codes you’re receiving and the codes you’re entering into the MyDyson may have got out of sync.
In the first instance, please wait 24 hours and then request for another code to be sent to you. Please ensure you don’t trigger further codes being sent until you’ve received and input the first one.
Ths should help, but if you continue to have difficulty after this point, please reach out to our regional Dyson Customer Care team for further support. For their contact details, please visit Dyson.com and click Support.
Hi Jack. Thanks for the answer. I've done that several times in the last 11 days. Support hasn't been in touch for 11 days either. I'm considering returning the light. I can't use the light fully without the app.
