(Savings Endpoint) Redemption history and Purchase history only returning past 2 weeks of data

I am trying to get all the historical purchase and redemption records using the Binance API. I am using a sliding window approach where I slide the date window down so it fits the requirements of querying a maximum of 30 days at a time. For some reason, however, I am only getting the past 4 weeks’ worth of data and when updating the time frame nothing is returned.

According to the API doc, there shouldn’t be a limit querying beyond last 30 days records, can you provide your full request URL with the parameters values please?
And do you confirm you can see the records on UI for the same date range and endingType?
