[Closed] Cart is not translated

Background of the issue:
I translated everything in string translations but it's still not translated in the cart. Checkout works ok. I enabled 'auto register strings for translations'. I scanned themes and plugins for new strings. I looked in 'Translate texts in admin screens'.

Symptoms:
Cart is not translated

Questions:
Why is the cart not translated despite translating everything in string translations?
Is there a specific step I missed in translating the cart strings?
