Привет) Almost everyone on the team speaks a language where this pronunciation is obvious (most prominently Russian and German, but it also works in e.g. Swedish).

I've noticed when talking to English native speakers that Brits seem to get it right away and say something close to "твикс", whereas Americans almost always say "tee-vix" ("тивикс") and need serious convincing work to switch over to how we say it.
