I don't have a fixed internet line at home and I want to use my phone hotspot to connect to my Deco BE65, so the Deco creates a wifi network connecting to my phone hotspot so that I can use connect other devices to the Deco wifi network.

The phone generating the hotspot is an iphone 14 Pro Max. The network provider is Three in the UK. 

I have gone through the online instructions to set up my Deco on Ap mode and reset it. Unfortunately after the Deco restarting, I don't get the 'More' menu on my app because the restart of the Deco deletes the network and ask me to configure my Deco network again.

The Deco stays with a red light from that point. The only way out it to reset it physically with a pin. That eventually gets the Deco discoverable by the app but it doesn't connect to my hotspot to create the wifi network from it. 

Can someone help, please. Thanks!
