It didn't seem that way when I read it in the brochure. It seemed like a very resistant and grateful plant, but obviously the soil type has to be appropriate.
The meter is excellent if you don't forget about it :)
Blueberries bear fruit in the second year, even if they skip the third, they should definitely give at least some fruit. Maybe you should really test the soil. It requires a pH of 4.2 to 4.8, maybe a little higher, but then it has to be fertile soil.
