Right Shift key not sending to Zoho Assist environments

Right Shift key not sending to Zoho Assist environments

I'm unable to use Right Shift key in Zoho environments. 
Zoho environments are Win10. Computer I access from is Win 11. Issue started when I changed to Win 11.

Have tried:
- Multiple browsers
- web client AND desktop client
- 3rd party mapping tools to force send
- Different environments (none allow Right Shift)

Google tells me there's a specific Win11 + Zoho input regression? Is there any way around this? It's driving me to drink!
