> Recent changes to EES system have been a disaster

How ?

> People do have to scan their biometrics more than once coming from a non-EU country.

If the data hasn't had time to propagate then it's just a flag that you need to do it.

> In some cases even if you are a EU resident in case the airport has no specific queues.

Yes, if I arrive in Firenze airport there is maybe 2 people working on the border, if I'm in the Schengen, I don't even need to be checked. I'm not sure what you're talking about.

> People without EU citizenship also enter EU.

Clearly I'm not talking about these cases. You're not from the EU, you need to follow the rules. Sorry.
