I understand the phones are Canadian versions. There is a lack of Russian or Ukrainian interface languages in comparison with Global versions of the phones. For example I can find the languages in the list but when I pick one of them the phone menu remains in English.
I checked iPhones and Google Pixels and there is no problems. The interface can be switched to any language.
Is it normal for $1500 phone? Extremely disappointed.
You're right, some Canadian models have limited system language support despite listing options like Russian or Ukrainian. It's a known regional firmware limitation, and we understand your disappointment. Hopefully, future updates can address this limitation.
