The thing that still blows my mind about the whole contact tracing solutions in Europe is that the servers do not federate with themselves, and that you can only keep a single country specific app active at the time. This leads to the situation where people that usually cross the country's borders will only use a single app which may not track all of the contacts. So far, the current solution is IMHO useless - but I keep on using it. In my case I just keep one app active at all time (the one from my home country), but it would be more effective if with a single app I was able to track the contacts with people from other countries too. Stupid simple example: I live in Switzerland (SwissCovid), and ideally when I cross the italian border I'll need to activate the italian contact tracing app (Immuni), but contacts with people that use a different app won't be counted even if they are infected - which totally misses the point of having a contact tracing in the first place :(
