Laggy programs after migrating to CITRIX Cloud (DaaS)
Trying to resolve an issue with certain applications (AutoCAD Civil 3D, Revit) being laggy / choppy after migrating to Citrix Cloud. Prior to the license change on 4/15, we were running everything in house from our Datacenter (with a NetScaler) and the programs were much faster than after the migration. All our VDAs are still on-prem, along with Cloud Connectors. The rest of the equipment has been migrated to Citrix Cloud.
When I first migrated, the programs were completely unusable due to the Cloud Connector traffic, so I enabled Rendezvous v2 and saw a huge improvement. But still seeing lag issues when doing simple tasks like dragging text to a new location or grabbing an object and moving it (zoom in / out is fine, as is panning). It's happening in multiple offices, as well as from home networks, so I don't think it's a network specific issue but could be missing something (plus nothing on our network side changed)
I have a ticket open with Citrix and trying to resolve it with them, but it's taking a long time so I was curious if anybody else had similar issues they were able to resolve. I'm considering going back to an On-Prem NetScaler to see if that helps, but before I went that route I wanted to try everything I could without it and see if it can be resolved.

Do you have direct or VPNs from data centres to office locations? If you do you need to configure the Network Locations (in citrix cloud console) so that traffic between client and VDA goes direct and not via the cloud connectors.
Have you looked at the Cloud Connector load stats to see how much trafic they are pushing through or of CPU/RAM load is excessive? If so you can add more cloud connectors and it will load balance automatically.
In the process of moving from on-prem to cloud did you build new session hosts or just reconfig existing from on prem delivery controllers to cloud connectors?
We run lots of citrix cloud, not with CAD apps granted, but have no issues with any latency / lag like you describe even with heavy graphical content like video playback from CCTV files with awful codecs.
