Mac OS Sonoma - Adding Web Apps in your Dock

Mac OS Sonoma - Adding Web Apps in your Dock

I'm testing Mac OS Sonoma before deployment across our organisation and found one of the most useful new features may have a significant bug - Web Apps on Dock

The new OS allows you to convert a webpage e.g. YouTube to an app like render once added to your Dock. When this is done, opening the newly created shortcut on your Dock renders it in a dedicated webpage. Full details can be found here - https://support.apple.com/en-ke/HT213583

In my testing...
  1. I added Zoho ONE as a web app on my local dock
  2. Opening the new App renders a brilliant uncluttered Zoho ONE web interface
  3. The issue I've experienced is
    1. Input interfaces fail e.g. opening/replying to an email allows access to the to, CC and Subject fields, but the main content/body interface cannot be accessed to add comment.
    2. Signature fails to load in the window.
Unlike Safari web pages, there do not appear to be any additional settings related to the page e.g. allowing/denying pop-ups etc.

Any advice/solutions for this would be welcomed :)
