issue retrieving data from interactive brokers

i'm using matlab 2021b with the most recent IB TWS, the example code provided by mathworks seems to run fine (no errors are produced), but no data is retrieved from IB.

%% connect to IB TWS

clear all; close all; clc

ib = ibtws('',7497);

%% Create the IContract Object

ibContract = ib.Handle.createContract;

ibContract.symbol = 'MSFT';

ibContract.secType = 'STK';

ibContract.exchange = 'SMART';

ibContract.primaryExchange = 'NASDAQ';

ibContract.currency = 'USD';

d = getdata(ib,ibContract)

%% request last 20 days of data

bizDayConvention = 13; % i.e. BUS/252

currentdate = today;

startDate = daysadd(currentdate,-20,bizDayConvention);

endDate = daysadd(currentdate,-1,bizDayConvention);

%%

histTradeData = history(ib,ibContract,startDate,endDate);

the same problem occurs when trying to retrieve live market data and create orders.

On a seperate note if someone from mathworks sees this, the documentation regarding Interactive Brokers needs updating/more detail adding as there is no documentation provided by IB for MATLAB.
