I was in a neighboring country in Europe at the time, not Ukraine, but we didn't see any Ukrainians move into our area until a few weeks after the war started.

That's not to say the country wasn't prepared though. If the GP did talk to people on the ground days before it started, saying it won't happen would match the public propaganda at the time coming out of the Ukrainian government and their allies. They knew it was coming and seemed to decide they were better to faint like the weren't ready and avoid public panic before it started.
