I suspect 2nd line support will take some time, to A. find the issue and B. resolve it.
Did you try adding an exclusion as I suggested.
I have never really been a fan of the ASB product, as by its nature, being a secure browser it limits what you can do with it and what add-ons you can include. For me that is a bit of a dark art as I don’t think it is clearly defined what it does to ensure that security and how it might interact with some sites, security related measures, such as Teams, etc.
