Live Chat throws errors on first open

Hi there!
We have an extensive integration with Hubspot and are looking to integrate the Livechat onto our customer-facing platform.
We load the hubspot tracking code through our GTM.
The live-chat is fully functional, however after any type of page-reload, opening the live-chat will throw throw three errors in the console and there is a failing http-request:

Request url:
https://app.hubspot.com/api/login-verify/hub-user-info?early=true&hs_static_app=embedded-viral-link-ui&hs_static_app_version=1.274&clienttimeout=3000
Request response:

{

“status”: “error”,

“message”: “app-cookie not engaged. App cookie is not present on the request.”,

“correlationId”: "some-id-here

}

What can I do to resolve these issues?
*edit:
I’ve seen this thread:
https://community.hubspot.com/t5/APIs-Integrations/Hubspot-Tracking-Code/m-p/361635?_ga=2.225907034.1190451373.1701427624-1199038256.1700035157
I’d like to add that I’m testing the live-chat integration in a Chrome incognito window, while being logged into our hubspot dashboard in Firefox.
Thank you for your time!
