There’s two ways you can get to your complete transaction history right now, if you’re on iOS you can use the search feature & then export the data as a CSV or QIF file.
You can also use the API to fetch the entire history but obviously that data needs to be reformatted - & again, this would be easiest to format as a spreadsheet - before it can be used.
Perhaps if you ask the support team, they can provide a ‘proper’ statement…please do let us know what they say, if you ask.
And maybe the web view will be built into the site that’s about to be developed too -
