I admire your ability to add Ukrainian to your languages in addition to Russian. I'm continuing to struggle, getting far too much interference between the cognates. I had the same problem when I tried to add Romanian to my French and (not great) Spanish - the similarities tripped up the differences and vice-versa. My brain is not adept at languages, but eventually - I hope - Ukrainian will come somewhat less awkwardly than it does at present. One huge motivation is to be able to listen to Zelensky and not keep having to pause & re-listed to work out the Ukrainian word I didn't properly get among the near-identical Russian cognates. But the key point is: no one really used to care what language was spoken; today, though, Russian is the language of the invaders and will always now carry a certain stigma.
