My Fenix 7X is unusable due to the problem with LAP button. The issues with buttons on 7 series are well known here in forums and elsewhere.
What is new is that the Garmin support have refused to provide service and did not want to confirm the warranty status of the watch, requesting proof of purchase.
In my case the watch was the gift - I have the box and everything but no receipt.
Here in EU it is illegal to refuse warranty and serial number and device use history are acceptables means of establishing proof of ownership under EU juresprudence.
If anyone is considering purchasing any Garmin product, I warn against about such decision.
