Thanks for the report, Isonation 
Any chance the 1904 update with Citrix Workspace now works for you if your work supports it? So far I’ve only seen two confirmed and it’ll be ideal to have an updated version that is compatible.
No worries if your work doesn’t support the 1904 version, just wanting more confirmations that the latest version fixes it. In any case, we’re fairly confident Version 4.12 and 1904 have been working so far!
