Right, oddly enough when I got UDP turned off my users actually said AVD felt better. Both technical users and the end users on the other end. Given 90% of our company is located in a 60 mile radius, the AVD infrastructure isn't exactly a stones throw away either. I'll take it as win.

That is interesting. Usually, you'll see the packet loss on TCP as the screen locks up, with scrolling draws of the screen as the TCP session retransmits or naggles and adjust the sliding window around.
It must be that shortpath just is not prime time ready, the UDP packet loss is enough to kill the connection on the Azure end but not bad enough to notice in TCP or something else. Like everyone in this thread, I go for periods where I have 0 issues. Then the disconnects pile on. Sadly, I need shortpath/UDP to be working as I tried pure TCP and the session latency wasn't working well for my end users. I've actually thought about bringing it back in house.

Do you use a NAT Gateway for the subnet?

We have disabled RDP Shortpath completely and switched back to TCP for stability and aid reconnect however we experience this issue as well for a fair few users everyday so we are keen to get to the bottom of this.

Jason_1995 Nope, I currently use Azure VWAN with a secured hub in a hub spoke architecture.
