Add GUID to each HTTP request and also show it in the diagnosis log. GUID is generated on first run or the app. We use X-Device-Id with uuid as custom header

The implementation looks good, let's see where to add it

Hi @PeterPetrik ,

Regarding how to send it, I would also be fine with it going in its own header, we should be able to accomodate that in the backend. This SE page may be useful for how to name a new one if we cannot find something appropriate to put it into.

Re the implementation itself, I have a question. I assume the UUID is automatically generated when the app is installed - is it subsequently readable and editable by the user? If so, I'm not sure this would be wise and I would instead opt for it to be stored in scoped storage or similar so it's protected from editing/cloning.

Looks like non standart headers might be blocked by firewall, what name you suggest?

Re implementation, only way how to reset it for user easily is to really remove the app completely and install from scratch.
