Strange TeamViewer User Agent - IE6!

Hi,

Wondered if anyone else had come across the fact that Team Viewer appear to deliberately pass through a User Agent that self identifies as an IE6 browser engine when it’s running through a Proxy like ZIA?

TeamViewer (Mozilla/4.0 (compatible; MSIE 6.0; DynGate))

This is preventing us from blocking IE6 use across all our users through ZIA Browser Control so open to any suggestions for dealing with this?

Otherwise it will be a colleague logging a ticket asking TeamViewer why they are doing this in 2021 - without any hope they will fix it!
