Zendesk Sell Notes API not returning all notes

Hello,

I am using the Zendesk Sell Notes API to get our notes from Zendesk. Unfortunately, since here is no parameter to fetch notes after a particular update or created date, I need to fetch all our notes every time. Not only is this slow to do so each time, but it appears that I am now missing data. The last note in my returned data is created 2023-04-11 10:57:48, when I know that more notes were written after that. 

When I call the endpoint, I loop through each page of the results and concatenate the data into one dataframe. This has worked fine for the 1.5 years we have been using Sell yet for some reason, I cannot fetch any data after 2023-04-11 10:57:48. 

Help would be appreciated here.
