When you are calculated fields (formulas, lookups or roll ups) into your app we will now infer their data type from Airtable. This means that they will be formatted correctly as if they weren't calculated fields.

Note: we aren't brining in all formatting options from Airtable at this time (e.g. decimal places, currency separators etc), however this change does mean that all currency formulas will now appear as currency fields in your app.
