I was able to find the onboarding screens. I am having some difficulty finding the remaining 3 strings in the app. In terms of the onboarding screens I tested, there are a couple of languages that need updating.

English - Appears to be fine

As with other strings in the app, these are translated by the volunteers at TranslateWiki (independently of our deadlines), and are automatically incorporated into the app at weekly increments (some can take much longer than others). I think it's acceptable to verify only the English variation of the string.

The other strings apply to the iOS app.

Makes sense to me, sorry for the churn.
