The end-to-end conversion rate for Pro(i.e. /upgrade(or /pro) to Pro sub) is ~5% lower in UK as compared to the US(8.5% in UK vs 13.1% in US - Source: Pro web funnel conversion rates in EMEA).
This may be due to a number of reasons:
Dropbox Pro may be too expensive for UK users. The majority of Pro users are wealthy. 58% of them make over $100k per year(Source:Pro 101). In the US more than 20% of the population has an annual income(pre-taxes) greater than $100k per year(Source:census.gov). In the UK the % of population making the same amount of money(£70k per year pre-taxes) is less than 5%(Source:gov.uk).
UK Basic users may store on average less content on Dropbox than US users and are therefore less likely to upgrade(87% of people who buy Pro do so because they need more space. - Source: Research what do new Pro subs think).
People who use Dropbox for work and have a VAT number(e.g. freelancers or business owners) need the VAT and the name of the company on the invoices in order to have the VAT refunded from the government. EU law might be stricter than the US law on this.
