It's a bit of a rigmarole in the beginning on PC, but I bet it's worse doing it on the mobile. I'm not surprised at the teething issues because this is the first time 99+% of those alive now have been in a global medical emergency. The real world logistics for delivering treatment and containment at this scale have yet to be learned, I think. I will say that I might be less willing to do this in a country with a decentralized private health system, like the US. I still value my medical privacy, and don't think I would be so trusting that it won't be exploited for profit in some way. I hold the concept of the NHS in pretty high esteem, even with the problems it has.
