(SOLVED) _w_ in shinyapps.io URL

Hi there, can anyone tell me more about the directory being added to the URL of my shinyapps.io app ending in /_w_123456/? Is this a version number?

We have a server side authentication solution that is based on the "clean" URL without that. Any guidance here would be great!

I should add that I'm looking to turn this off - the w param is stripping authentication tokens from the URL

Problem solved, this was an issue from tablerDash (a Shiny implementation of tabler.io), specifically in this init.js file
